initial page creation

New page

== Overview ==

Ethernet (TCP) and Modbus (RS-485) interfaced 8-channel relay output and 10 optocoupler input module.

== Software ==

There is Chinese software to configure the MAC address, IP address, Modbus baud-rate, etc.

== Factory Reset Button ==

The tactile button is hooked to pin 93 (PB7) of the microcontroller, it is used for factory reset.

== Debug Interface ==

Header labeled "P2":
