After 3 successive orders, the bases have all three a defect of connectivity.
I think the heights of the pins of the contacts are not high enough and do not fit in the header.

It's M5 who has to make the changes?
If not, where can I find the drawing of the changes?
I am a teacher in France who wants to use your products for science education computer and I want to find practical solutions.

Thank you

I'd like to update my question on M5GO Base. From a more careful reading of the schematic diagram the Vout on the IP5306 of the M5GO Base is not connected to the +5V. In this case the IP5306 of the base has no conflict with the one inside the M5Stack Core.

Hi @Engin is the code you tried which didn't work https://github.com/m5stack/Bases-Node/tree/master/example/dht12 the only other code examples I could find for the node were in Chinese and Japanese, maybe if you use google translate you could find some useful info https://github.com/m5stack/esp-adf/blob/master/examples/get-started/M5Node/main/play_mp3_example.c

@lukasmaximus said in BTC 2.0 not powering the basic M5Stack:

@gadjet sorry this was definitely an issue with the description. The btc ticker is not capable of charging the m5 stack.

I wouldn't mind but I bought two of them !!! Oh well back to my 3D printed stand and a big battery.
