Read More…Audio preamplifier with differential input for bluetooth modules based on OVC3860 chip, in my case:
I made this (based on online documentation, and reverssing from pictures of discontinued product) just for easy development, becaose output ground of this modules can't be connected to power ground ( it has 0.9V offset, in case of OV3860 based modules)
also this could work with F-3188 BLE bluetooth 4.0 module based on CSR8645
It used 12V, I used NE5532 (no luck with LM358), but you can used whatever you want. Also I can populate it or give you parts.
