DC-DC 5Vto2x12V Converter Board

An USB powerd DC-DC Converter that provides +12V and -12V. It's based on the RECOM REC1.5-0512DR/X1 you can by for example at Pollin.de. The board has two control LEDs. Both are 2V, 1mA Low Current LEDs. If you have diffrent LEDs you have to change the 10kOhm resistor.

For the modification of the Mini-USB socket one have to cut the spare pins:
