My homebrew P15 power board provides unmonitored power and is a stripped down version of the C11 power board. The main purpose of this card is to operate as a decoder tester/programmer via a USB connection to the PC. No external power supply is required as it can be powered via the USB and the optional isolated DC/DC converter.
