<![CDATA[Can't get working core2 with ac power base]]>Hi all!
I bought a couple of ac power bases and core2 controllers, connected them and can't get them to work. When connecting 220 volts, the controller does not turn on and clicks are periodically heard. When I power the controllers via usb, they work great. Can anyone help me connect?

hmm, not sure what is going on then and unfortunately I cannot try this myself as I don't have an ac power base on hand. Sorry.

Maybe check with M5Stack support directly?

Thanks
Felix

upon starting up the M5Core2 5 V pin on the M5Stack bus is set as input, then depending on the program running, the 5 V pin might be switched to an output. If that is the case, then the M5Core2 keeps restarting as it shuts itself off, as soon as the 5 V pin is switched to an output.

however if you use the latest Arduino M5Core2 library for your program, there is an automatic detection for external power and if present the 5 V pin is kept as an input. See here.

Thanks
Felix
