The SparkFun Pro Micro RP2040 is a low-cost, high-performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the good 'ol Pro Micro footprint, the board also includes a WS2812B addressable LED, boot button, reset button, Qwiic connector, USB-C, resettable PTC fuse, and castellated pads.
The RP2040 utilizes dual ARM Cortex-M0+ processors (up to 133MHz) and features:
264kB of embedded SRAM in six banks
6 dedicated IO for SPI Flash (supporting XIP)
30 multifunction GPIO
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 with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. The built-in USB can act as both device and host. It has two symmetric cores and high internal bandwidth, making it useful for signal processing and video. While the chip has a large amount of internal RAM, the board includes an additional 16MB external QSPI flash chip to store program code.
6 dedicated IO for QSPI flash, supporting execute in place (XIP)
