Welcome! This is the newest edition of the Orpheus Pico - an RP2040-based development board, similar to a Raspberry Pi Pico.
The Orpheus Pico 2 features:
- Identical footprint to the Raspberry Pi Pico
- an RP2040 microcontroller
- 32 addressable GPIO pins
- onboard active-high LED (IO25)
- onboard RGB LED (IO24)
- USB-C connection
- high-current power lines
- and more!
There have been many major changes from earlier versions of the Orpheus Pico! Several notable ones are:
- epic new silkscreen!
- higher power capability (thickened a bunch of power traces that caused overheating)
- new voltage regulator which doesn't overheat
- dimmed the onboard leds
- significantly improved grounding, meaning lower-impedance path to ground
- made the crystal on the rp2040 more stable
- general cleanup of routing and components

Usage of the Orpheus Pico almost completely matches that of a Raspberry Pi Pico. You can use several different frameworks, such as the Pico SDK in C++, Arduino, or Micro/Circuitpython. Some board specific stuff:
- onboard active-high LED on IO25
- onboard RGB LED on IO24
- user-configurable button on IO23 (use a pullup in code)
The RGB led can be controlled as a typical neopixel. You can use libraries like the Adafruit Neopixel library in C++.
