Empower your data connections with our custom FTDI
cable assembly solutions. Each cable integrates a
genuine FTDI USB converter IC for plug-and-play
serial connectivity.
FTDI cable assembly that use integrated circuit
chips, like FTDI converters, can give you important
benefits. The internal IC chip takes care of the USB
protocol and clock recovery, making sure that data
conversion is stable and error-free. This lets any
USB port act like a native serial port while sending
and receiving data in the UART, RS232, and other
formats. Using USB+IC makes things even more
compatible. FTDI chips connect a common COM port to
the host system. The company also provides free
drivers for a number of operating systems, such as
Windows, macOS, Linux, and embedded systems. In
reality, an FTDI cable is almost plug-and-play. The
FTDI IC keeps connections stable even when using
older TTL devices because it can automatically set
the baud rate, buffer data, and translate voltage
levels. Built-in FTDI chips often have useful
features like internal regulators, customizable CBUS
pins, and a unique Chip-ID for security.
Every FTDI cable assembly has a full-speed USB
connection and precise signal levels. For
instance, the FT232 series from FTDI works with
USB2.0 (12 Mbps) and UART speeds up to 3 Mbaud.
Most serial links can use a USB-FTDI cable that
runs at 12 Mbps USB to send serial data securely
at about 3 Mbps. For a single FTDI RS-485 cable,
the highest bus rating is 3 Mbaud. This
hardware-level conversion gets rid of jitter and
bit-slipping, unlike unprocessed bit-banged
methods.
New chips use for each cable
We have never bought fake chips or used old ones
again. Each cable of the FTDI cable assembly is
made with a brand-new FTDI chip (FT232R/FT230X
or something similar). FTDI has even warned
about fake FT232 devices that are out there, so
we only buy from authorized sellers. With real
FTDI parts, you can count on consistent
performance and support. The unique security ID
that comes with FTDI chips is another way to
stop cloning. This means that you can be sure
that our cables will always work with the newest
firmware.
Custom made service
We make cables that are perfect for each
project. We can change the length, wire gauge,
pin assignments, shielding, and connector types.
Do you need an M12 stainless steel connector or
an overmold? Not a problem for us. We encourage
prototypes and short runs because our minimum
order quantity (MOQ) is low. Do you like cable
coloring by the pair or custom packaging? Your
specifications tell the factory what to make. It
will happen. Our service also includes
engineering help to make sure that every FTDI
cable works as it should. This includes
everything from looking over the design to fully
testing it.
Our cables use copper wire because it lasts longer
and works better. Standard FTDI cables use 28 AWG
stranded copper, which is the best mix of
flexibility and current capacity. For situations
that need a lot of power or speed, we can use a
thicker gauge. Plating the conductors with tin or
nickel keeps them from rusting. For low capacitance,
you can insulate each conductor separately with PE
or XLPE, and then cover the whole bundle with a PVC
or LSZH jacket. The end result is a cable that can
handle bending and other everyday use without
breaking.
FTDI USB overmolding plastic
Overmolding the housing of the USB connection is
common to make it last longer. You can overmold
materials like PVC, TPE, or rubber-like compounds. A
good overmold should help relieve stress so that the
cable doesn't break at the plug. When you order a
mold, you can choose between a rough texture and a
softer rubber for better grip. Panel-mount versions
can use metal connections to shield. You can also
choose clear or colored overmolds or add logos to
the mold for a custom FTDI cable assembly.
Everything is made to meet the safety standards and
RoHS rules that apply.
FTDI cable shielding request
You can change the shielding on each FTDI cable to
fit your EMI needs. Foil shields (copper/aluminum
tape) are great for places with a lot of
high-frequency interference because they cover
everything 100%. Braided shields are made of tinned
copper braid and are strong and quiet at low
frequencies. You can use connector shells to end
shields, or you can ground another pin with an
exposed drain wire. The best way to protect yourself
is with a mix of foil and braid. To deal with EMI
issues, just give the right amount of shielding for
military or industrial use.
What kind of USB connector can be made for FTDI
FTDI cable assemblies come with a lot of different
USB plugs, so you should be able to find one that
fits your device. The most common connections are
between a USB-A male (host side) and a 6-pin TTL
female. We also make cables with USB-B or USB-A
female connectors for connecting devices. Smaller
devices use Micro or Mini USB connectors. USB-C has
become more popular in the last few years. Adafruit,
for instance, sells both a USB-C FTDI cable and a
micro USB to TTL FTDI adapter. You can use any kind
of locking mechanism or connection orientation you
want. We can even put the FTDI circuitry inside a
jack housing that is already on a board. If you need
a regular Type-A, Micro-B, Micro-USB-B, USB-C, or
even an industrial USB connection with a screw-lock,
just let us know, and we'll take care of it.
FTDI imported chips and Taiwan chips differences
USB-serial chips are not all the same. FTDI chips,
which come from the UK-based company FTDI Chip, are
known for being very stable and reliable. On the
other hand, "Taiwan" chips, like Prolific's PL2303,
have a bad reputation and are known to cause driver
problems. Our FTDI cable assemblies only use
original FTDI integrated circuits. This guarantees
that drivers will act consistently and get a lot of
support. Clone chips don't have features that are
common in FTDI chips, such as unique device IDs
(Chip-IDs). Simply put, real FTDI chips work as
promised, but fake or non-FTDI chips may stop
working after a firmware update or have drivers that
don't work well.
FTDI featured converter cables
We sell prefabricated FTDI converter cables (FTDI cable
assembly) that work with standard interfaces. You only
need a USB port; these cables will send the serial
signals. All you have to do to use any of the
highlighted cables is plug them into a USB port. You
don't need any more boxes or power.
FTDI USB convert to TTL
This cable can get you the normal TTL UART
signals: RTS, TX, RX, CTS, VCC, and GND.
SparkFun calls it a "USB to Serial (TTL level)
converter" because it makes it easy to connect
TTL interface devices to USB. It works well with
Arduino, ESP, and other boards with
microcontrollers. RTS, RX, TX, 5V, CTS, and GND
are all there, as they usually are. It works
with standard 6-pin headers. You can get both 5V
and 3.3V logic versions. For instance, the
Adafruit USB-C FTDI cable uses 5V power and 3.3V
logic signals. You can also get them with custom
wire ends, which means the ends are bare wires.
This FTDI cable assembly has an 8P8C RJ45
connector on the end and is meant to be used as
a Cisco console cable. It has an FTDI chipset
that changes USB levels to RS-232 levels after
switching to the RJ45 connector. Cable Matters
says, "The built-in FTDI chipset takes care of
the USB signaling, which includes an RS-232
level shifter." The usual way to do this is to
connect a computer's USB port to a switch or
router port. This cable looks like a Cisco
rollover cable, but it sends USB signals instead
of Ethernet signals. With the help of FTDI
drivers, it can be seen as a virtual COM port.
You can use these cables to set up network
devices, and they work with Windows, Linux, and
Mac computers because they come with a driver.
Pick from our selection of USB to RS485 cables
for differential serial. For example, the FTDI
USB-RS485-WE cable uses an FT232R with an RS-485
transceiver built in. This 1.8-meter cable is
industrial-grade and connects a USB port to a
2-wire RS-485 bus. It is CE and FCC approved.
The A and B signal cables are given to the user
without ends so that they can connect them to
their own cables. It makes a separate COM port
with a bandwidth of up to 3 MBaud and gets its
power from USB. This lets you connect a PC to
RS-485 networks (PLCs, sensors) without needing
any extra hardware. You can use the same idea
with USB-to-RS232 or RS422 FTDI connections if
you need to.
FTDI cables help computers connect to factory
machines. These machines include PLCs and CNC
tools. The cables work with different power
levels from 1.8V to 5V. They are built to handle
electrical noise. People use them to set up
machines and collect information.
Medical & Healthcare
Hospitals and labs use FTDI cable assemblies to
link medical devices to computers. These cables
help move data in a safe way. Some cables have
special medical-grade covers to add extra
safety.
IoT & Embedded Systems
Students and engineers use FTDI cable assembly
with boards like Arduino, Raspberry Pi, and
ESP32. The cables help them program and test
their projects. They connect with easy 6-pin
plugs and can also give power to the device.
Telecom & Networking
FTDI cables help workers set up and fix routers
and network switches. They allow new laptops to
connect to older equipment that uses serial
ports.
Testing, Education & Automotive
FTDI cables are often used in schools, labs, and
cars. They are helpful for learning kits, test
tools, car computers, robots, and sensors.
Wide Voltage Level Support
Our FTDI cable assembly covers all common TTL voltage
levels:
1.8V Output
For low-voltage interfaces (some modern
microcontrollers, SDRAM, ASICs). Cables like
FT232RG-VREG1V8 output exactly 1.8V on
TX/RX.
3.3V Output
Standard for most embedded boards (Arduino
Pro Mini, Raspberry Pi UART, ESP, etc.). For
example, TTL-232R-3V3 cables give 3.3V
logic. Adafruit’s FTDI USB-C cable has 3.3V
TX/RX lines (with a 5V power line) for this
reason.
5V Output
Needed for classic TTL and 5V
microcontrollers. TTL-232R-5V cables provide
5V logic. Useful when interfacing older
digital circuits or powering 5V boards.
Some cables even support a range (TTL-232RG-VIP
supports 1.8V–5.25V logic), which can be adjusted
via an onboard regulator. In short, whether your
target device runs at USB to TTL 5V vs 3.3V logic,
we have a matching cable.
Genuine FTDI Chip Integration & Driver Support
Every FTDI cable assembly uses a genuine FTDI
converter chip, ensuring top-tier compatibility.
FTDI chips come with fully supported drivers. In
fact, all FTDI cables “use FTDI royalty-free drivers
– available on Windows, MAC, Linux, and WinCE”. This
means when you plug in our cable on any modern OS,
it immediately appears as a COM port. Drivers are
included in Windows 10/11 and recent macOS by
default, and Linux kernels have built-in support. No
mysterious third-party drivers or hacks are needed.
Engineering support from FTDI means easy
maintenance, too. As noted, many FTDI chips include
a built-in FTDI chip ID security feature. This
hardware ID can be set by the user to secure the
cable, helping prevent counterfeit or unauthorized
usage. Using authentic FTDI cable assembly parts
also ensures you can update firmware or EEPROM
settings using FTDI’s tools. In practice, working
with these cables is trouble-free thanks to the
broad, well-tested FTDI driver ecosystem.
OEM/ODM: Custom Labeling & Marking
OEM/ODM Customization
We offer a full range of OEM and ODM
customization services. Add your logo to our
custom-made FTDI cables. You can put your brand
on the jacket or connector of the cable.
Custom Labeling
You can add your product ID or brand name to the
labels on each cable if you want to. We can
either wrap the cable with printed labels or
laser-etch your brand or part number into the
mold if you want it to stay on the cable.
Heat-Shrink Marking
Put text or pictures on heat-shrink sleeves or
labels that will last a long time. This is a
good way to put a compliance mark, serial
number, or barcode on each cable.
Part Number Printing
Printing the model numbers or batch identifiers
on the jacket makes it easy to keep track of
your cables. This is a common way to tell what
kind of cable it is in a factory.
With these branding options, you can have your custom FTDI
cable assembly manufacturer's name or part scheme put on
every cable we send. The scheme is built into every cable we
deliver.
Recensioni dei clienti
I needed a USB to UART cable wire ended for an embedded project, and QL’s FTDI cable was perfect. It arrived fast, and the bare wires were clean and easy to solder. Works great with my Raspberry Pi and Arduino. No driver hassles on Windows or Linux.
John Smith
The USB-C FTDI cable we got from QL is well-built. We use it to flash firmware on custom PCB prototypes. It matched the FT232RL pinout 6 pin standard, so hooking it up was seamless. QL also printed our logo on each cable – very professional!
Emily Zhang
Excellent FTDI cable assembly. I ordered a batch of USB-to-TTL cables (one 3.3V, one 5V) to replace broken ones at our lab. They worked as advertised. On MacOS (including the new Sequoia release) they show up immediately thanks to built-in FTDI drivers. No bricking issues like with other knock-offs.
Michael Brown
QL’s custom labeling is handy. Each FTDI cable has our part number and logo on the jacket. They even heat-shrink marked the ends with wire IDs. The cables are rugged – I’ve yanked on them a lot and no problems. Customer service was very helpful when I had a question about voltage level.
Sarah Johnson
Our networking team loves the FTDI console cables (USB to RJ45) from QL. They use them daily for router configs. The built-in FTDI chip really simplifies setup. QL met our request for bend-relief overmolds, which helps in tight rack spaces. Solid performance and compatibility.
David Lee
We needed a waterproof industrial FTDI cable for a field sensor project. QL delivered an IP67-rated cable with armored jacket. It survived outdoor testing in rain and dust. The price was very reasonable given the rugged spec. We’ll definitely work with QL again for custom cables.
