Waveshare RP2350-USB-A Development Board – RP2350A Dual-Core MCU

The Waveshare RP2350-USB-A is a compact RP2350A development board designed for embedded applications, USB projects, robotics, IoT devices, and electronics prototyping.

At its core is the RP2350A microcontroller, featuring a unique dual-core and dual-architecture design. Developers can work with dual-core Arm Cortex-M33 processors or dual-core Hazard3 RISC-V processors, with operating speeds of up to 150MHz.

The board includes 520KB SRAM, 2MB onboard Flash, 15 multifunction GPIO pins, and a range of hardware interfaces including SPI, I2C, UART, ADC and PWM.

A key feature is its onboard USB Type-A expansion port, which uses PIO-USB and supports USB 2.0/1.1 transmission. The board also has a USB Type-C connector for programming and USB connectivity.

The castellated PCB edges allow the module to be soldered directly onto a carrier board or custom PCB, making it particularly useful for product development and embedded integration.
