FS: PI2design 502DAC, raspberry Pi HAT

Price update: Asking for $40 including shipping. only the board, no case. Will ship within U.S. continent (48 states) only. Friends and contributors for now. will consider $45 for rando members.

This is the version P3. Slightly different layout compared to the P4 version. There is a headphone socket, but it doesn't work. The RCA (DAC signals) and all the digital outputs (BNC, AES, Optical) are working. It is not a broken board but an early batch. And no, this is not an prototype neither. I purchased from Pi2Design. The later P4 (current) version removed the headphone socket. Cheers.

1) WM8804 with GPIO selectable 24.5476Mhz/22.5792Mhz Clock input
2) Clock are very low noise using NDK2520SD series.
3) WM8804 runs in Master Mode, Pi in Slave mode so BCLK and LRCLK are very low jitter
4) Transformer coupled Coax and Optical SPDIF output
5) LT3042 Ultra-Low Noise, High PSRR LDO for SPDIF PLL and Crystal supply
6) Jumper to isolate Pi 5V from Hat 5V for external 5V input
7) 4-Layer PCB with filtered ground from Pi

 

Price dropped to $40 for Friends and Contributors. Will also consider $45 for Rando members.
