The SparkFun RP2350 Pro Micro offers a robust development platform in a compact form factor, featuring the RP2350 microcontroller from the Raspberry Pi Foundation. This updated board includes a USB-C connector, Qwiic connector, WS2812B addressable RGB LED, Boot and Reset buttons, a resettable PTC fuse, and both PTH and castellated solder pads.The RP2350 stands out with its dual-core microcontroller architecture, comprising two ARM® Cortex® M33 processors and two Hazard3 RISC-V processors, running up to 150 MHz. Users can select which two processors to activate at boot, allowing for flexible performance configurations. The microcontroller also boasts 520kB SRAM across ten banks and a suite of peripherals, including two UARTs, two SPI, and two I²C controllers, as well as a USB 1.1 controller for host and device support.Additionally, this board includes 16MB of external Flash and 8MB PSRAM, connected via the RP2350's QSPI controller, supporting development in both C/C++ using the Pico SDK and MicroPython environments.The SparkFun Qwiic Connect System simplifies prototyping with its ecosystem of I²C sensors, actuators, shields, and cables. Utilizing a 1mm pitch, 4-pin JST connector, this system reduces PCB space requirements and ensures error-free, polarized connections.Features:RP2350 Features * Dual ARM Cortex M33 and Hazard3 RISC-V Processors * User-selectable for dual-cores * 520kB integrated SRAM in 10 banks * 3.3V-tolerant GPIO * Peripherals * 2x UART * 2x SPI * 2x I²C * 24x PWM Channels * 12x PIO State Machines SparkFun Pro Micro - RP2350 Features * RP2350 Microcontroller * 8MB PSRAM * 16MB Flash * Supply Voltage * USB: 5V * RAW: 5.3V MAX * Pro Micro Pinout * 2x UART * 1x SPI * 10x GPIO (4 used for UART1 and UART0) * 4x Analog * USB-C Connector * USB 1.1 Host/Device Support * Qwiic Connector * Buttons * Reset * Boot * LEDs * WS2812 Addressable RGB LED * Red Power LED * Dimensions: 33.02mm x 17.78mm Documents: * Schematic * Eagle Files * Board Dimensions * Hookup Guide * MicroPython Firmware UF2 (Early Release) * SparkFun Pico SDK Library * RP2350 Datasheet * APS6404L PSRAM Datasheet * RP2350 Product Brief * Raspberry Pi RP2350 Microcontroller Documentation * Qwiic Info Page * GitHub Repository Videos https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-01-24 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-05-22 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-05-23 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-09-29 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-09-30 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2025-12-19 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-01-09 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-01-23 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-01-31 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-02-05 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-02-11 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-02-19 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-03-05 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-03-12 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-03-17 https://elecena.pl/product/27751512/sparkfun-pro-micro-rp2350 2026-04-13
