@kimot No, it is an obvious mistake, I am very sorry. Maybe it is becouse the code in master branch is very old, the newest is not yet on github, but the developement branch is quite new. I am going to fix this soon.

This is ethernet gateway for RS485 (wired) MySensors nodes. It features ATmega328p MCU and ENC28J60 ethernet chip. SP485EE or similar IC is used as RS485 transceiver. It works on hardware serial to ensure more stability and to achieve higher baud rates.
The board itself is designed with having thermal issues in mind, since the ENC28J60 draws a lot of current. It features two 10-pin IDC sockets, one to connect external PCB with LEDs (Power, TX, RX, Error) and RESET button, and one for programming (MOSI, MISO, SCK, TX, RX, 5V, GND). Its size makes it case compatible with Raspberry Pi.
This work is a part of our RS485 module system.
We will place typical questions and answers here, if they occur.
