Product description: SparkFun Pro Micro - RP2040 - SparkFun DEV-18288
A small board from SparkFun based on Raspberry Pi RP2040 microcontroller with ARM Cortex M0+ Dual-Core clocked at 133 MHz. It features 264 kB of SRAM, 6 dedicated IO pins for SPI Flash memory, 30 GPIO pins, USB Host / Device port via USB Type-C. The manufacturer has also included a Qwiic port, Reset and Boot button and an addressable RGB LED on the board.
The RP2040 microcontroller can be programmed in both C/C++ and MicroPython. It has UF2 booting and floating point routines built in. Although the board is equipped with a lot of RAM, there is an additional chip with 16 MB QSPI Flash memory for program code storage. The board is also equipped with a Qwiic connector, which allows easy connection of modules and sensors equipped with the same connector, with an I2C interface.
