This is mostly a “ethernet connected device” to allow network access to up to 4 relays, or LED strips for example.
It is a carrier board for one of the really cheap “Arduino Pro Mini” you can buy for 1.99 GBP on ebay.
It has a slot for a ENC28J60 ethernet module (ebay again, about 3 GBP) that installs itself underneath.
It has 2 (optionals) TC4427 dual FET drivers, to drive relays directly, or a FET to control large LED arrays. The 4 FET are routed to the edge connector.
It also has a Maxim DS2483 i2c to Onewire master, to hook up one or mode temperature sensors and the like. Also routed to the edge connector.
The serial port is also routed to the edge connector, as well as the ISP of the processor.
Furthermore, you can select the voltage of the arduino with a jumper, so you can run it all at 3.3, or at 5V.

This is a dual output switching power supply based on TI’s TPS54383 capable of delivering upto 3A of current on both outputs at the same time. Switching frequency is 300KHz with a 600KHz drop-in replacement also available. Take a look at my instructable for putting this together here - http://www.instructables.com/id/High-efficiency-dual-voltage-3A-power-supply/

Small breakout protoboard for -> http://www.buydisplay.com/default/mp3-oled.html
using the built in regulator. Pins/caps should be reasonably obvious if you compare it to the schematic in the “interface” datasheet. Untested so far.
