We’ve talked about Ethernet basics, and we’ve talked about equipment you will find with Ethernet. However, that’s obviously not all – you also need to know how to add Ethernet …read more Continue reading Ethernet For Hackers: Transformers, MACs And PHYs
The ESP32 is the latest and greatest wonderchip from Espressif. It’s a 32-bit, dual-core chip with WiFi, Bluetooth, and tons of peripherals such as CAN and Ethernet. For most of these peripherals, Espressif already has a few bits of example code, but [Frank Sautter] didn’t like the Ethernet implementation. The ‘stock’ code calls for a TLK110 Ethernet PHY, but that’s an expensive chip when bought in quantity one. A better chip would be the LAN8720, so [Frank] built a board to enable Ethernet on the ESP32 with this chip.
The ESP32 only needs a few components to wire it into …read more
