*GitHub : https://github.com/rdiot/rdiot-s058.git

* Specs

The ENC28J60 Ethernet Module utilizes the new Microchip ENC28J60 Stand-Alone Ethernet Controller IC featuring a host of features to handle most of the network protocol requirements. The board connects directly to most microcontrollers with a standard SPI interface with a transfer speed of up to 20MHz.

ENC28J60 Ethernet chips, SOP28 package

SPI Interface

2X5 connector, can be easily mounted with the MCU
