W5500

An ESP32-S3 DMX box that receives Art-Net over UDP 6454 through a W5500 and drives two DMX512 universes via MAX485, for about $29,33 in parts.

A GPS 1 PPS pulse disciplines an ESP32-S3 clock to ~5 µs; the W5500 SPI Ethernet path is timestamped so LAN clients see 60–100 µs.

Newsan Lab's ArchiNet adds W5500 wired Ethernet plus ESP32-S3 Wi-Fi/BLE to its mass-produced ARCHI RP2040 education board, with open KiCad files.
