![]() ![]() Just a few resistors, capacitors, and an RJ45 jack will take care of most of the work, but because he’s taking the Ethernet ‘shield’ route, he needs to add his own Ethernet PHY. The ESP32 only needs a few components to wire it into an Ethernet network. A better chip would be the LAN8720, so built a board to enable Ethernet on the ESP32 with this chip. The ‘stock’ code calls for a TLK110 Ethernet PHY, but that’s an expensive chip when bought in quantity one. ![]() For most of these peripherals, Espressif already has a few bits of example code, but didn’t like the Ethernet implementation. It’s a 32-bit, dual-core chip with WiFi, Bluetooth, and tons of peripherals such as CAN and Ethernet. ![]() The ESP32 is the latest and greatest wonderchip from Espressif. ![]()
