LORDWORLD RP2350-ETH Mini Development Board

SKU CH-BADC-KVJMS

Compact development board with dual-core RP2350 microcontroller, built-in Ethernet via CH9120, 520KB SRAM, 4MB flash, and 14 GPIO pins compatible with Pico HATs

  • Dual-core RP2350 runs up to 150 MHz for responsive edge processing
  • CH9120 handles TCP/IP in hardware so Ethernet works without a software stack
  • 520 KB SRAM plus 4 MB Flash store firmware and buffers locally
  • 14 GPIO pins plus 12 PIO state machines fit many Pico HATs and custom peripherals
  • Drag-and-drop USB programming and castellated edges simplify development and board integration

RP2350 Ethernet Dev Board

The LORDWORLD RP2350-ETH is a compact development board built around the RP2350 dual-core microcontroller. It integrates Arm Cortex-M33 and Hazard 3 RISC-V processors running up to 150 MHz. An onboard CH9120 chip provides a hardware TCP/IP stack for wired Ethernet connectivity. The board includes 520KB SRAM and 4MB Flash memory for application storage.

Makers needing wired networking

This board suits developers building IoT edge devices that require a reliable physical network link without external shields. It also fits engineers evaluating the RP2350 dual-architecture performance for custom peripheral design using 12 PIO state machines. Projects dependent on native Wi-Fi or Bluetooth radio must look elsewhere, as the hardware provides only the Ethernet interface. Buyers needing more than 14 GPIO pins for dense HAT stacking should also consider other form factors.

CH9120 TCP/IP offload

The CH9120 handles the full TCP/IP protocol stack in hardware, freeing the RP2350 cores for application logic instead of network packet processing. This single specification determines whether the board meets the real-time deterministic requirements of your specific embedded control system.

Questions about this item

Will the 4 MB onboard Flash on the RP2350-ETH board wear out and need replacement?

The 4 MB Flash is soldered to the board and rated for typical embedded write cycles; it is not a user-replaceable part, so the board itself would be replaced if the Flash fails.

What limits sustained throughput on the CH9120 Ethernet link?

The CH9120 handles the TCP/IP stack in hardware, so sustained throughput is bounded by the RP2350 dual-core running at 150 MHz and the 520 KB SRAM available for packet buffers.

How hot does the RP2350-ETH get when the Ethernet port runs continuously?

The RP2350 dual-core at 150 MHz and the CH9120 Ethernet chip draw modest power; the board has no active cooling, so it runs warm but stays within normal embedded operating temperatures.
