LORDWORLD RP2040-ETH Mini Development Board

SKU CH-G0SY-XDA6T

Tiny RP2040 development board with an onboard Ethernet port and castellated holes for embedded integration

  • Dual-core RP2040 processor handles real-time IoT tasks
  • Onboard Ethernet port enables wired network communication
  • Castellated holes with gold finish simplify board integration
  • Supports TCP server, TCP client, UDP server and UDP
  • C/C++, MicroPython and Arduino environments supported with full SDK

Compact RP2040 board with Ethernet

The LORDWORLD RP2040-ETH is a tiny development board built around the RP2040 dual-core microcontroller. It adds a wired Ethernet port for reliable network connectivity in embedded projects. Castellated holes with immersion gold allow direct soldering onto a host PCB or use with standard headers. The board targets makers and engineers who need a small Ethernet-enabled controller.

Onboard Ethernet port for wired networking

The single specification that determines fit is the integrated Ethernet interface, which supports TCP server, TCP client, UDP server and UDP communication modes. This provides a hardwired network link without relying on Wi-Fi or external modules. The RP2040 core handles the protocol stack while the PHY manages the physical layer.

USB-C power and castellated mounting

The board draws power and provides a serial console through its USB-C connector. Castellated pads let you embed the module directly into a custom PCB, freeing up board space compared to a separate Ethernet shield. Software development is supported in C/C++, MicroPython and Arduino with SDKs, tutorials and example code supplied. Buyers who need wireless connectivity or additional GPIO headers not exposed on this module should look elsewhere.

Questions about this item

What does the dual-core 2040 processor deliver in a real build?

The dual-core 2040 runs C/C++, MicroPython and Arduino code, handling TCP server, TCP client, UDP server and UDP traffic on the wired Ethernet port.

What does the Ethernet interface cap in practice?

The board provides a single Ethernet port supporting TCP server, TCP client, UDP server and UDP modes; throughput is limited by the 2040 microcontroller and the physical link.

What do the castellated holes need for mounting?

Castellated holes with immersion gold finish are designed for reflow soldering directly onto a host PCB.
