LORDWORLD Ethernet to UART Converter 2-CH 10/100M 802.3 development board

Pico-series Ethernet bridge

The LORDWORLD development board adds wired networking to Raspberry Pi Pico microcontrollers through a standard 40-pin header. It integrates an Ethernet MAC and PHY so the Pico can send and receive data over a local network without extra modules. Makers building remote sensors, industrial loggers or home-automation nodes can drop the board onto an existing Pico project and gain immediate LAN connectivity. The two independent UART channels keep serial streams separate for multi-device setups.

Dual-channel transparent UART

Each of the two UART channels operates independently with standalone transparent transmission between serial and Ethernet frames. Onboard jumpers let you remap the TX, RX and control pins to match your firmware without soldering. The converter handles bi-directional data flow automatically, so microcontroller code reads and writes ordinary serial bytes while the board manages packetisation, checksums and link negotiation. No protocol stack is required on the Pico side.

Low-power 10/100M operation

The 802.3-compliant interface auto-negotiates 10 or 100 megabits per second in full-duplex or half-duplex mode and supports Auto-MDI/MDIX for straight or crossover cables. DHCP obtains an IP address and DNS resolution without static configuration. The PHY draws minimal current during idle periods and scales with traffic, so battery-powered or PoE-split designs stay within tight power budgets. No fan or heatsink is needed in normal indoor environments.
