A low-cost USB to serial MIDI converter using an RP2040 and CircuitPython #RaspberryPi #CircuitPython @Raspberry_Pi @sandyjmacdonald

Sandy Macdonald posts about making a low-cost RP2040-based USB to serial MIDI converter. It uses a Pimoroni Tiny 2040 board, a SparkFun stereo jack breakout, and a couple of resistors. 

Less than £10 worth of bits, and could be less than £7 if you used a basic stereo jack.

11 lines of CircuitPython code. Here’s an arpeggio from Orca being sent to the Make Noise 0-coast. It should work with both flavours of MIDI over 3.5mm stereo cables (swap the 3v3 and Tx pins around) or MIDI cables if you wire in a DIN connector.

See this Twitter thread and the code on GitHub.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
