Pico / RP2040

The Pico is a dual core microcontroler and a board designed by the Raspberry-Pi foundation. With an afforable price, the Pico could make a revolution in the MicroControler world (as the Pi does for nano computers). The Pico does have many GPIOs, common buses (SPI, I2C, UART) and NeoPixel support. You can program it with C/C++ or with MicroPython (Yahoo!)... it is a OpenSource plateform. The board does have an extensive documentation and the full support of the Raspberry-Pi foundation.
