Has anyone here used the Sensirion AGP30, a tiny I2C sensor for CO2 and VOC gases? It takes about 60mA to heat a hot plate, and it needs at least 15 seconds to start reading data. But ours is experiencing shutoffs after 1.8 seconds when we run it from a Feather, but not if we run it from a Raspberry Pi. Both controllers feed the PCB with 3.3 volts, where its regulated down to 1.8 volts with an TPS71718. We communicate with the IC fine in both cases, and get the readings, but they're wrong if the hot-plate won't stay on for 15-seconds.
