ESP8266 and ESP32 compatible firmware to read, interpret and publish data to MQTT from smart electrical meters, both DLMS and DSMR is supported

This is an Ethernet PHY board based on Andy Brown board.
Phyether is an open-source printed circuit board by acassis, from the acassis/phyether repository on GitHub, published under the MIT licence. It is a 2-layer board with 43 parts on 59 nets, routed with 345 tracks and 10 vias.
It is built around the RJ45. Its parts include 19 resistors, 13 capacitors, 4 connectors, 3 diodes and 2 inductors. It belongs with the interfaces and adapters boards of this library.

I used KiCAD to develop this board. KiCAD is open-source and it is a very powerful EDA software.

43 parts, built around the RJ45. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the acassis/phyether repository on GitHub, at the commit this page was made from: the board is ethernet/phyether.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
