Waveshare has announced four new USB-C and USB-A development boards based on the Raspberry Pi RP2350 MCU: the Waveshare RP2350-Plus dev board, the Waveshare RP2350-Zero Mini dev board, the Waveshare RP2350-ETH Mini dev board, and the Waveshare RP2350-GEEK USB dev board.
The RP2350-Plus is a low-cost, high-performance Pico-like development board with the RP2350 MCU, various I/O, battery support, USB Type-C, and compatibility with Raspberry Pi Pico modules. The RP2350-Zero Mini is another compact dev board with castellated pins, 29 GPIOs, USB Type-C, PIO, and versatile peripheral support, ideal for IoT, robotics, and embedded systems. The RP2350-ETH Mini dev board has Ethernet support and various GPIO functionalities, making it ideal for IoT development. Like any other RP2350 board, the Waveshare RP2350 boards support C/C++ and MicroPython SDKs with drag-and-drop firmware flashing via USB mass storage.
Waveshare RP2350-Plus development board
The Waveshare RP2350-Plus is a low-cost development board that comes in a Raspberry Pi Pico form factor and it’s built around the Raspberry Pi RP2350A MCU with 4MB flash, a USB 1.1 Type-C connector for power and programming, and castellated and through holes with 26 multifunction GPIOs, ADC, PWM, UART, SPI, and I2C. The main difference is that the Waveshare board can be powered by a lithium battery and hosts an onboard DC-DC buck-boost chip for stable operations.
With its flexible GPIO, battery support, efficiency, power management, and customizable features like programmable I/O, the board is suitable for prototyping IoT devices, embedded systems, and educational purposes. More information about the product may soon be found on its Wiki page (currently empty).
The Waveshare RP2350-Plus development board can be purchased from AliExpress for $7.61, and on Amazon for $12.99. You’ll also find it on the official Waveshare store.
Waveshare RP2350-Zero Mini USB-C Development Board
The Waveshare RP2350-Zero Mini is another development board based on the Raspberry Pi RP2350A chip. The board includes 4MB of onboard flash, a USB Type-C port for programming and power, and castellated edges for surface mounting. It features 29 GPIO pins, 12 programmable I/O (PIO) state machines, and interfaces like SPI, I2C, UART, ADC, and PWM. Additional features include low-power modes, a temperature sensor, and an RGB LED.
Its tiny size (23.5 x 18 mm) and features make it suitable for space-constrained applications like IoT, robotics, embedded systems, and custom peripherals development where space is an issue. The Wiki is also empty right now, but the product page has more details.
The Waveshare RP2350-Zero Mini development board can be purchased on AliExpress for $5.39, and on Amazon for $11.99. It provides an alternative to the XIAO RP2350 USB-C board (21 x 17.5 mm) from Seeed Studio with a slightly bigger design but a few extra castellated I/Os.
Waveshare RP2350-ETH Mini Development Board
Last but not least, Waveshare also released the RP2350-ETH Mini development board, which is another RP2350-powered development board but this board has a 10M full duplex serial ethernet chip onboard (CH9120) making it suitable for IoT and networking applications. The board supports multiple communication modes, including TCP Server/Client and UDP, and features 14 GPIO pins for connecting peripherals. The board also features a USB Type-C port for power and programming and castellated holes for soldering onto carrier boards.
These features are suitable for applications including IoT devices, network-enabled embedded systems, and custom hardware solutions requiring Ethernet connectivity. Once again, the wiki has no information whatsoever, but you can find more details on the product page.
The Waveshare RP2350-ETH Mini development board can be purchased for $13.49 on AliExpress and $19.99 on Amazon. It’s not the first RP2350 board with Ethernet, as we previously covered WIZnet W5100S-EVB-Pico2 and W5500-EVB-Pico2.
