The SparkFun Pro Micro RP2040 is an affordable and high-performance development board with flexible digital connections and the Raspberry Pi Foundation RP2040 microcontroller. In addition to the familiar Pro Micro footprint, the PCB also includes a WS2812B addressable LED, a power button, a reset button, a Qwiic connector, USB-C, a resettable PTC fuse, and castellated pads.

The RP2040 uses two ARM Cortex-M0+ processors (up to 133 MHz) and has the following features:

• 264 kB of embedded SRAM in six banks.
• Six IOs dedicated to SPI flash (supports XIP).
• 30 multi-function GPIOs
  • Dedicated hardware for commonly used peripherals.
  • Programmable IO for extended peripheral support.
  • Four-channel ADC with internal temperature sensor, 0,5 MSa/s, 12-bit conversion.
• USB 1.1 host/device

The RP2040 is supported by both C/C++ and MicroPython toolchains, including easy access to runtime debugging. It has UF2 boot and drag-and-drop routines built into the chip. The built-in USB can operate as both device and host. It features two symmetric cores and high internal bandwidth, making it useful for signal processing and video. The chip has a large amount of internal RAM, and the board also includes a 16 Mb external QSPI flash chip for storing program code.
