should be ok as long as you are not selling it.

@bazman Fix is to delete the line! Both the microphone example and the factory test project then work.

Great ! Thanks @flypeek

@bazman Here is the StickC API link:https://docs.m5stack.com/en/api/stickc/axp192_m5stickc

I ordered another C-Plus today and got the v1.1 revision as expected. There's a difference on the label - Sleep/Wake has been added next to the RTC box, see below. I would like to know what the relevance of this change is. [image: 1676992895200-m5stick-cplus-diffs-resized.jpg]

Anyone found out the differences between 1.0 and 1.1 for M5StickC Plus ?

Hello @bazman according to the schematic the power button only is connected to the AXP192 and not to an ESP32 GPIO as are buttons A and B. Luckily the AXP192 can be setup to detect the power button short / long press via interrupt. Checkout the AXP192 datasheet - you can find it here. The AXP192 registers dealing with short / long power button press interrupts are 0x42 (IRQ enable 3) and 0x46 (IRQ status 3). Thanks Felix
