RP2350-MINI

RP2350-MINI: RP2350A Dual-Core Microcontroller – Raspberry Pi-Based

The RP2350-MINI development board is built with the RP2350A dual-core microcontroller based on the Raspberry Pi architecture. The board features a single-sided surface-mount and through-hole design, with a compact PCB size, making it highly convenient for users to directly solder and integrate into custom-designed baseboards. It also supports 2.54mm pitch header pins for easy connection to custom baseboards. The board includes a Type-C port, RGB LED, reset button, and BOOT button, providing excellent flexibility for development and debugging. This development board is ideal for maker projects, embedded system development, and DIY electronic products.
