@dclaar I have no problem with the Stamp-PICO running on the 3.3V power from the programmer. And the StampS3 running on USB 5V actually outputs out 3.3V at the RGB output... So, YES!

@ameero95 said in M5StickC Plus cant drive an Adafruit sensor module (3.3V) through the Grove port using the Grove to STEMMA QT adapter.: STEMMA QT try level shifter maybe?

@ajb2k3 That's great news, thanks a 1,000,000
