Hello @orfait

you can try to stack a different module (like a proto module) in between.

Yes, same here, the antenna was connected to the incorrect socket as well.

Thanks

Hello @bmtd111

I think the WiFi connection configured via M5Burner only works as long as code is temporarily run on a device. In app mode though the WiFi connection might be lost if not executed within the UIFlow.

Please see this thread.

Hello @brianteeman

the documentation is probably not fully up-to-date.

Maybe checkout the description here.

Also have a look at this example.

Thanks

Hello @keiichiro1192

yes, the 100 mA are due to a setting. Line 1880 in this file.

M5.Axp.SetCHGCurrent(AXP192::kCHG_100mA);

Thanks

Hello @Trevman

I am afraid M5Core2 and GoPlus2 are not fully compatible. Please see this thread.

Thanks

Hello @greenleaf

glad to hear it worked.

Thanks

Hello @TapM

the AXP192 does automatically switch between ACIN (USB) , VBUS (5 V pin on M-bus) and battery. However in your case only VBUS and battery are in the mix.

I did some experiments (i.e. turning on internal 5 V boost w/o disabling VBUS) and yes, switching on the internal 5 V booster while power comes in via 5 V pin on M-bus immediately shuts the system down. My best guess is, that the AXP192 doesn't like the 'circle' that is created in that way, e.g. kind of powering itself through the internal 5 V booster.

Not sure if there is a way to solve this w/o hardware modification.

Thanks

Hello @greenleaf

from the M5Stamp Pico documentation, section Program Download.

STAMP-PICO adopts the most streamlined circuit design, so it does not include the program download circuit, users can download the program through the USB-TTL burner.

If you don't have the USB-TTL burner board, in order to use M5Burner or esptool, you'll need to put the M5Stamp Pico into download mode manually by connecting a wire from GPIO0 to GND before powering it up. (For regular boot, the wire needs to be removed again.)

Hello @SirMichael

I think most is described here.

Hello @mchott

I could be wrong but I don't think you can. PaHub extends I2C, however the HX711 in the weigh unit is not an I2C device. See schematic.

Thanks
