'''[[Microduino-ENC28J60]]''' must be stacked with '''[[Microduino-RJ45]]''' together to form a complete Ethernet module, individual module can not be used seperately. 

'''[[Microduino-ENC28J60]]''' module is based on Microchip’s ENC28J60 stand-alone 10Base-T Ethernet controller. The ENC28J60 is a stand-alone Ethernet controller with an industry standard Serial Peripheral Interface (SPI). It is designed to serve as an Ethernet network interface for any controller equipped with SPI.

'''[[Microduino-RJ45]]''' is the common name for an 8P8C modular connector using 8 conductors. It has dedicated pins for LED link and network activity indication. 

'''[[Microduino-ENC28J60]]''' meets all of the IEEE 802.3 specifications. It also provides an internal DMA module for fast data throughput and hardware assisted checksum calculation, which is used in various network protocols. Communication with the host controller is implemented via an interrupt pin, if required, and the SPI, with clock rates of up to 20 MHz.

'''[[Microduino-ENC28J60]]''' + '''[[Microduino-RJ45]]''' provide onboard low drop voltage regulator which supplies stable voltage to the Ethernet controller. It is an ideal device for applications involving Home/Office Automation, Remote Diagnostics systems, Industrial equipments, Security Systems and Robotics as well.
