What's under the hood?The Op3n dott don't want to reinvent the wheel. As you can see he used the well known CSR-8635 module. Limited Datasheet and tools for flashing available on the net,not bad! And what about the sound quality?Not too bad but if you want to get some nice quality tones probably you will be disappointed.
