How do I turn off my M5StickC PLUS2?
To power on the device, press and hold “Button C” for more than 2 seconds, or trigger the IRQ signal by the RTC regularly. After triggering the wake-up signal, set the HOLD (GPIO4) pin to a high level (1) during program initialization to maintain the power supply. Otherwise, the device will enter the shutdown state again.
Power off:
When no USB external power supply is available, press and hold “Button C” for more than 6 seconds. Alternatively, when there is no USB external power supply, set HOLD (GPIO4) to 0 during program operation to power off the device. When the USB is connected, press and hold “Button C” for more than 6 seconds to turn off the screen and enter hibernation mode, but not power off the device.

| M5STICKC PLUS | ESP32-PICO-D4 | AXP192 | 120mAh | 520KB SRAM and 4MB Flash | CH522 | orange red |
| M5STICKC PLUS2 | ESP32-PICO-V3-02 | \ | 200mAh | 2MB PSRAM and 8 MB flash | CH9102 | orange |
Pin difference
| Product Name | IR | LED | TFT | BUTTON A | BUTTON B | BUTTON C(WAKE) | HOLD | Battery Voltage Detection |
|---|---|---|---|---|---|---|---|---|
| M5STICKC PLUS | G9 | G10 | MOSI(G15) CLK(G13) DC(G23) RST(G18) CS(G5) | G37 | G39 | Normal buttons, non-programmable | / | Read via AXP192 configuration |

The difference between turn on and off
| Product Name | Power on | Power off |
|---|---|---|
| M5STICKC PLUS | Press the reset BUTTON (BUTTON C) for at least 2 seconds | Press the reset BUTTON (BUTTON C) for at least 6 seconds |
| M5STICKC PLUS2 | It can be started by pressing “BUTTON C” for more than 2 seconds, or IRQ signal triggered by RTC regularly. After triggering the wake up signal, it is necessary to set the hold(G4) pin to high level (1) in program initialization to maintain the power supply, otherwise the device will enter the shutdown state again. | When no USB external power supply is available, press BUTTON C for more than 6 seconds. Or when there is no USB external power supply, set HOLD(GPIO4)=0 in the program operation, that is, to achieve power off. When the USB is connected, press the “BUTTON C” button for more than 6 seconds to turn off the screen and enter the hibernation state, but not power off. |
Since M5StickC PLUS2 has cancelled the PMIC power management chip AXP192, the switching mode will be different. As mentioned in the beginning of the article, the operation is the same, so the library files supported by the program will also be different. Both the Wi-Fi signal and the infrared signal are stronger than before.
