The FTDI Friend is more versatile than the FTDI TTL-232R cable, but I wanted something that could do even more. Sometimes 4 UART signals just isn’t enough. So I took the FTDI Friend design and added the features I needed. All 8 UART signals and 2 CBUS signals are available on a 2×6 connector. There is also a power LED. Edge and thru-hole pads allow for a variety of connection options. Routing the board was a challenge because all the via had to be clear of the pads on the back and all the silk text.
The front of the board has a power LED and the six pin serial connection has been duplicated on rectangular pads.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
