Does Piano DAC use the RS232 TTL pins from RPI3 ? We want to use the RS232 (pin 8 and 10) on the RPI 3.
Is there a breakout for these pins on the Piano board ? If we don't want to plug in the Piano board what are the connections that needs to go from RPI3 to the PIANO ? just power and I2S ?

Can you please share the Technical Document for the Piano DAC, the document is for Piano 2.1. Is there a link where these documents are listed ?
