      It appears this board does not contain the serial EEPROM required for the Raspberry Pi HAT specification. Can you confirm?

      It seems that many HATs does not have EEPROM. If I'm not mistaken it's optional, and even if it's there it's usually useless.

      Hi, I use this board on top of the Raspberry PI Zero W, and it can not even run the google-assistant-demo, the error msg is "google.assistant.library.assistant.UnsupportedPlatformError: armv6l is not supported".

      Don't hold your breath. I (and several others) have playback issues with the speed being too fast. ZERO response from Seed forum or Seed itself.

      The button triggered demo worked for me. I believe there is a limitation of the google-assistant-sdk for running hotwords on zero.My next attempt will be to use a hot word from https://snowboy.kitt.ai/

      Is it correct that using the JST connector for audio out I only get mono sound while using the 3.5mm audio jack I get stereo?

      Both JST connecter and 3.5m audio jack can stream audio output, are support stereo.Did you try ALSA cmd to setting?

      Xiaobo - you are wrong. There are only two pins on the JST audio connector and stereo would require 4 pins. A quick check of the schematic link shows the JST connector is wired to the right channel; the left channel LP (low power) connections on the WM8960 IC are not connected to anything. Looks like Seeed rushed to get this design out without fully thinking the design through.

      I got the answer from the technical support :It communicates through I2S (Inter-IC Sound) and it uses the pins : GPIO18 (pin 12), GPIO20 (pin 38), GPIO21 (pin 40) and GPIO19 (pin35)
