Raspberry Pi i2s hat with Raspberry Pi power conditioner -- deal at PD 2-3 June

selling my spare Rpi hats. both are unused SG$100

I am in Singapore, and will be in Port Dickson during the weekend of 2-3 June if you like to deal there.

1) i2s hat which takes input from RPi and converts to i2s and SPDIF. There is no USB in the chain to there is least jitter in the digital outputs.
This i2s hat also functions as a standalone DDC allows to route from SPDIF input to i2s out. Imagine the possibilities, you can even connect your TV optical out to this hat and i2s out to your DAC.
