That looks like quite the module. If ordering from the TinySine link you can specify the antenna type (wire/U.FL or SMA) and TWS vs multipoint (aka party or mirroring) modes. For my own personal use I'd prefer I2S vs analog outputs. But that's just me. I'd really get excited if TinySine included an I2S version of this board in one of their integrated amps that also have DSP.
Thanks. How do you connect I2S to an amplifier? I need a miniature class-d 150w mono.

Some chips like the MA12070P accept I2S inputs directly. In my case the DSP (ADAU1701) accepts analog and I2S inputs. Using I2S from the blue tooth chip prevents the extra D/A and A/D steps when converting from digital to analog and back to digital. The TinySine TSA7800B amp has a blue tooth module that outputs I2S to the DSP. It supports AptX and TWS, but not the newer AptX versions and not multipoint.
Thanks. I my case I need to make it mono, that with analog output only requires 2 parallel 2k resistors (that won't do with TWS though)
