Does the Google Assistant SDK also work on a "Pi 2 Model B" (ARM Cortex-A7, a 32bit processor), or is a "Pi 3 Model B" ( ARM Cortex-A53, 64bit processor) essential to get the SDK up and running ?
It's working properly on a Raspberry Pi 2. I'm using it with my Logitech c920's mic.
I am running the Voice Kit that was in the MagPi Magazine on a Raspberry PI Zero W, so it should run fine on almost all the Pi's https://aiyprojects.withgoogle.com/voice/
