I have 7 of these free to a good home should they be useful to anyone. They are minimum order/surplus to needs and might make a handy little distribution board.

A look over the board should answer most questions.

There is provision for two voltage adjustable outputs (board annotated with resistor vs voltage calc and part name) a fixed 12v output an 8v camera power output/or whatever value regulator is installed (TO-252). There is also provision for a fixed 5v supply (TO-252) - output will need to be tapped from a convenient location.

There are two tmp36 temperature sensor inputs and provision for 4 x pushbuttons.

If used with a Teensy 2.0 (Arduino compatible) it has two PWM outputs and controls the adjustable voltage outputs.

The board has 4x mounting holes or it may be housed in a Canon BG-E5 battery grip.

While the board was designed to control a thermoelectric cooling system, power the camera and provide dew heating x 2, it is quite flexible.

SMD pad size is mainly 1206, which is manageable for hand soldering.

EDIT: There is provision for a mosfet - I use an IRF7430-7 - a 7 pin DPAK-2

PM me if interested, questions...
