Hello guys,
Thinking about latest versions of BlueSAAB and AMP, I wanted to integrate the amplifier on main PCB. That requires to remove the less used parts of the module : USB Firmware update of RN52 and factory reset switch. I don't think Microchip would update it any time and the tricky factory reset procedure would so rarely be used, in my opinion.
Assuming that, I did a partial redesign of the board, moving the MIC socket and RN52 (Seth,who did lots of tests may answer "it won't work due to antenna clearances requirements" but I tried to comply with them) and integrating the THS4522 circuit. Some labels from RN52 are a bit blocked by UART pins and it would need a little extra work to move it between MCP2525 and THS4522 to free more space...
Before continuing in this way, I summit it to your expert eyes. @Karlis, Seth, Sam, feel free to tell what you think about it. I did this for fun and challenge but if it suits you, I'll be glad to continue further.
