Waveshare RP2350B-Plus-W development board

Waveshare RP2350B-Plus-W is a development board built around the Pi RP2350B dual-core MCU. It features Wi-Fi 4 and Bluetooth 5.2 connectivity, along with access to all the GPIOS os the MCU, making it ideal for IoT, embedded, and educational projects.

The board features a dual-core setup with either ARM Cortex-M33 or Hazard3 RISC-V cores running up to 150 MHz, 520KB SRAM, and 16MB Flash memory with optional PSRAM expansion. It includes the Raspberry Pi Radio Module 2 for wireless connectivity, a USB Type-C for power, programming, dual user LEDs, BOOT and RESET buttons, and a low-dropout regulator. Developers get access to all 41 GPIO pins, multiple I2C, SPI, UART, and ADC channels, 12 PIO state machines, and onboard sensors with this compact yet feature-rich development board.
