Description
The Waveshare RP2350-USB-A Mini Development Board is a powerful yet ultra-compact development platform built around the Raspberry Pi RP2350A microcontroller. Designed for engineers, students, makers, and embedded developers, it combines high performance with a small footprint, making it ideal for space-constrained applications.
The RP2350A features an innovative dual-core, dual-architecture design, allowing developers to use either dual-core Arm Cortex-M33 processors or dual-core Hazard3 RISC-V processors, operating at speeds of up to 150MHz. This flexible architecture makes the board suitable for a wide range of embedded and real-time applications.
The board includes both a USB Type-C port for programming and power, and an onboard USB Type-A expansion port implemented via the RP2350’s Programmable I/O (PIO), enabling USB host and device applications. It also features 2MB Flash memory, 520KB SRAM, an onboard RGB LED, reset and boot buttons, and castellated edges for direct soldering into custom PCBs.
Compatible with C/C++, Arduino IDE, and MicroPython, the RP2350-USB-A provides an excellent platform for learning embedded programming, developing USB peripherals, creating IoT devices, robotics projects, industrial controllers, and custom hardware solutions.
