Description

Power control module for portable bluetooth speaker. Features: - Reverse polarity protection - Low voltage shutoff (arduino controlled) - Unstable power shutoff (arduino controlled) - Single button on/off control - MOSFET switches can drive high power DC-DC converters - Two sequenced high power outputs (Amp power + Bluetooth/DSP power) - Mute input (for disable amp power when no bluetooth connection) - Zero power draw when shut off Arduino Nano sketch attached.
