Waveshare RP2350-ETH Mini Development Board - reliable development board with Ethernet
A miniature development board based on the official RP2350 microcontroller. The Waveshare RP2350-ETH provides an embedded TCP/IP stack thanks to the CH9120 chip, making it ideal for projects requiring stable and fast network communication. Its small size, functionality and ease of integration make it ideal for both prototyping and final commercial applications.
Key features
- Official RP2350 microcontroller - developed by Raspberry Pi, featuring a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V core (four cores in total).
- Built-in TCP/IP stack - the CH9120 chip allows easy management of network parameters (mode, port, IP) via software and commands sent via the serial port.
- Fast programming - the device is recognised by the PC as a USB mass storage device, so code can be uploaded by drag-and-drop.
- 14 multi-functional GPIO pins - arranged on a small board, with edge-mounted half-hole (castellated) pinout for easy installation in projects.
- Flexible frequency - clocked up to 150 MHz, providing the performance needed for a wide range of applications.
- On-board memory - 520 KB of SRAM and 4 MB of on-board Flash memory allow storage and execution of complex programs.
