I've just ordered a Le Potato board. The main reason for this purchase is to make a car infotainment system.
So I have a couple of questions which might be interesting for other people as well

  1. Since the Le Potato board has dedicated ADC and I2S pins for digital audio I wanted to know if there are any I2S DACs that are confirmed to work with the board?
    I researched a bit and the layout of Le Potato seems quite similar to Hardkernel's Odroid C2 (based on amlogic s905) which has I2S pins in the same location. Any clue if the DAC hat for C2 will fit the Le Potato board?
    Here is the link to the DAC

    I will use AOSP 8.0 build with the board. Does Android have native support for I2S digital audio?

  2. Is there any option to shut down the board using GPIO pins?
    Some boards have dedicated PWR pin which can be shorted with GND to initiate shutdown process or call a power off menu. (Odroid XU4 for instance). Is there anything like that in Le Potato? Also is it possible to initiate deep sleep instead of full shutdown?

  3. Are there any usb GPS modules that are confirmed to work with this board?
