Choo! Choo! This is the RP2040 Metro Line, making all station stops at “Dual Cortex M0+ mountain”, “264K RAM round-about” and “16 Megabytes of Flash town”. This train is piled high with hardware that complements the Raspberry Pi RP2040 chip to make it an excellent development board for projects that want Arduino-shape-compatibility or just need the extra space and debugging ports.
RP2040 main chip, 133MHz clock, 3.3V logic
16 MB of QSPI flash for program storage
24 GPIO, 4 of which are also analog inputs
Micro SD card wired up for SPI interfacing, and also has extra pins connected for advanced-user SDIO interfacing (note that there’s no released usage code for SDIO in Arduino/Python, so this is a super-cutting-edge setup).
Onboard RGB NeoPixel
Onboard #13 LED
STEMMA QT/Qwiic port for I2C peripherals and sensors
