Hello,
I am making a Bluetooth portable speaker with the krc-86b Bluetooth module and the PAM8610 amp. The amp works fine when I don't use the Bluetooth board, and instead just use an aux cable.
But when I try with the bluetooth board the amp draws 0.5A though the AGND pin on the krc-86b, its really peculiar and means the krc-86b board turns off as I guessing a safety feature stops it.
Not sure what I am doing wrong, the amp has a 3 pole 3.5mm jack input, and I have bought a 3.5mm screw terminal (

krc-86b to amp:
OutL to L
OutR to R
AGND to GND
If anyone can help, would be much appreciated.
