SparkFun Pro Micro - RP2350

The SparkFun RP2350 Pro Micro brings the incredible power of the Raspberry Pi RP2350 microcontroller to our classic compact Pro Micro form factor. This board is a fantastic upgrade for any project combining massive processing flexibility abundant memory and modern features like USB-C and Qwiic all in a tiny breadboard-friendly (and surface-mountable!) package.The RP2350: Unprecedented Core FlexibilityThe star of the show is the Raspberry Pi RP2350 which redefines processing flexibility. This microcontroller provides a unique dual-core setup that allows you to select in software which cores you want to run:A pair of Arm® Cortex-M33 coresA pair of Hazard3 RISC-V coresOr one of each!All cores can run up to 150 MHz. This isn't a quad-core MCU; instead you select at boot which two processors you want to run allowing you to develop and test on two different architectures with a single board. The RP2350 also features 520kB of SRAM two UARTs two SPI controllers two I2C controllers and a USB 1.1 controller supporting both host and device modes.Modern Compact and Ready to BuildWe've updated the Pro Micro form factor with all the features you need for modern development:USB-C Connector: A robust reversible connector for power and programming.Qwiic Connector: A built-in Qwiic connector gives you plug-and-play access to the entire SparkFun Qwiic ecosystem of sensors displays and actuators.WS2812B RGB LED: An onboard addressable RGB LED for user status.Boot & Reset Buttons: Easy access buttons for programming and restarts.PTC Fuse: A resettable fuse protects the board from overcurrent.Massive Memory in a Micro FootprintDespite its small size the RP2350 Pro Micro is packed with memory. It includes 16MB of external Flash and 8MB of PSRAM connected to the RP2350's QSPI controller giving you more than enough room for complex MicroPython applications large data buffers or extensive Arduino code.Flexible Integration: PTH & Castellated PadsThis board is designed for any application. It includes standard 0.1"-spaced Plated Through-Hole (PTH) pins for use with headers in a breadboard. It also features castellated edges allowing you to surface-mount the entire Pro Micro directly onto a parent PCB for a low-profile permanent installation.Multi-Platform Software SupportThe RP2350 Pro Micro is built for all developers. It has full software support for C/C++ using the Raspberry Pi Pico SDK MicroPython and the Arduino environment so you can choose the programming language and environment you prefer.
