      When I first started up my M5StickC, an error message appeared like "Error 21, AXP find error, check hardware" or something like that. Does anyone have a solution for that problem? Thanks

        Hello @ozehnder

        looking at the factory test source code, error 0x21 appears when the AXP192 temperature reading either is below 5 or above 90 - which is used as an indicator that communication with AXP192 cannot be established.

        I probably would try to run the AXP192 example to see if the AXP192 really refuses to communicate and if yes contact the store for a replacement.

        Thanks
