HW (pcb, schematics etc) for my projects

Breadboard adapter for F-3188 ----------------------------- Breadboard adapter for F-3188 bluetooth audio module from ebay/aliexpress (search for F-3188) based on CSR8645 chip.

v2: - buttons for PLAY, NEXT, PREVIOUS, VOLUME UP and DOWN - 3th led - usb microusb + protection circute - microphone support circute

v1: - reset + MFB button (based on schematics provided for module, this should be button, but based on tests it should be switch, solder jumper is on board to bypass button) - 3.5mm jack for audio output - indication leds
