We purchased 10 of these kits for $149 each. The buttons/sensors have 4pin connectors but there’s nowhere to plug them into! Found out I need a Grove Base Hat for RasPi !!! Why is this not included with the kit !!! ??? Is this an oversight? What is work-around?
ok, I found there’s an I2C interface when plugging the RESPEAKER in. We’re supposed to use that interface
