PRO2+ Power Supply

Just a quick note re the power supply for your Pro2+ receiver.  You will note on the PCB that it states 9V DC power input.  Some of the 'wall-wart' or 'plug-pack' style power supplies are "unregulated" meaning that under no or little load the outlput voltage will float high, and in some cases I have see upwards of 14v and 15v on a so called 9v PSU.  Therefore you want to get yourself a "regulated" 9V DC power supply and it will output a steady 9V supply.

Although the specs on the Mega2560 Pro Mini module say 7 - 12V power input, we need to consider the other modules on the board.  After talking with Werk it seems that the TX modules can burn-out if receiving 12V for too long.

If your not sure about a PSU that you may have sitting around, just check it with a mulitmeter "before" you use it. If you seeing a nice 9v DC reading on your meter, then all good...

As for current draw, it is advised to get at least a 1A PSU, if not larger, to cater for the total current draw on all of the modules and the backlight on the screen.  A 1.5A suppply will be a safe bet, and the one I found at the local Altronics store was 2A, so no worries there.
