The organization has introduced the Raspberry Pi Pico, a $4 board meant to offer a gentle entry point for microcontrollers. Think of it more as a complement to a Pi aimed at tasks like analog input.

The Arduino Nano and Raspberry Pi Pico have distinct pin configurations. The Nano includes 14 digital pins (for both digital input and digital output components) and eight analog pins.

[Pelham] coded a library to parse MIDI messages on the Pico, with the microcontroller’s UART charged with receiving the input data. MIDI is basically just serial at a baud rate of 31.25k, with a ...

Since the Raspberry Pi Pico 2 also supports 3V input, prepare a power supply that can output 3V. Additionally, we also have a desktop multimeter.

Code written and compiled in Code can be debugged on the Pico over a wired connection to your host Pi. The combination of Raspberry Pi and Visual Studio Code is a powerful one.

All that’s hiding inside that heavy-duty plastic box is the Pi Pico and some screw down terminals that let [Alberto] easily wire up the female bulkhead connectors for the pedals themselves.

Raspberry Pi details the three-year journey behind its new RP2040 chip, which was designed in-house and manufactured by iPhone chipmaker TSMC.
