Raspberry Pi Foundation currently offers RP2040 as their MCU offering which is supported in OpenDeck firmware. This MCU is used on Raspberry Pi Pico development board and many others.
- External flash memory (2/4/8/16MB)
- 264kB of RAM
- Supported interfaces:
- 2 UART channels
- 2 I2C channels
RP2040 uses semi-flexible pin mapping for peripherals. The table below lists all possible pin combinations for supported UART channels.
| Rx | Tx |
|---|---|
| GP1 | GP0 |
| GP13 | GP12 |
| GP17 | GP16 |
| GP5 | GP4 |
| GP9 | GP8 |
