mikroETH Additional Board
The mikroETH additional board is used to connect a microcontroller to Ethernet network. mikroETH is connected to the development
system via a proto board, but it can also be directly connected to the microcontroller provided in some device. The mikroETH board
features three connectors. Two male 1x5 connectors are used for connection with the proto board or a device, while the RJ45
connector is used for connection with Ethernet network.
Communication between the microcontroller and Ethernet network is established via the ENC28J60 ethernet controller provided on
the mikroETH board. This controller enables data to be transferred from Ethernet network to the microcontroller and vice versa using
serial SPI communication. In Figure 4, the mikroETH board is connected to the microcontroller via the SPI communication module
built into the microcontroller.
