We are looking for a cheap and efficient way to charge the amplifier and the Bluetooth module. We are trying to use a remastered version of the Minty Boost from Adafruit to deliver a 3V-voltage to the Bluetooth module and a 12V-voltage to the amplifier. Not working well though, the current is far too high from what we should observe according to our calculation. The sound from the speakers is very noisy.
