Power On/Off ⚡
Power On:
- Press the "BUTTON C" button for more than 2 seconds.
- Alternatively, wake up via an IRQ signal triggered by the RTC timer. If using the RTC wake-up signal, the program must set the HOLD (GPIO4) pin to high (1) during initialization to maintain power; otherwise, the device will re-enter the power-off state.
Power Off:
- When there is no external USB power supply, press the "BUTTON C" button for more than 6 seconds.
- When there is no external USB power supply, set HOLD (GPIO4) to 0 in the program to power off.
- When connected to USB, pressing the "BUTTON C" button for more than 6 seconds turns off the screen and enters sleep mode, but does not fully power off the device.

Power On/Off Differences ?
| Product Name | Power On | Power Off |
|---|---|---|
| StickC-Plus | Press the reset button (BUTTON C) for at least 2 seconds. | Press the reset button (BUTTON C) for at least 6 seconds. |
| StickC-Plus2 | Can be powered on by pressing the "BUTTON C" for more than 2 seconds, or by an RTC-timed IRQ signal. After the wake-up signal is triggered, the hold (G4) pin must be set high (1) during program initialization to maintain power, otherwise the device will shut off again. | Without external USB power, press the "BUTTON C" for more than 6 seconds. Alternatively, if not powered by USB, setting HOLD(GPIO4)=0 during program execution will completely power off the device. When connected to USB, pressing the "BUTTON C" for more than 6 seconds will turn off the display and put it into sleep mode, but will not fully power off the device. |
Since the StickC-Plus2 has removed the PMIC power management chip AXP192, the power on/off methods differ slightly. While operations are largely similar, supported firmware libraries will vary. Both Wi-Fi and infrared signal strengths have been improved compared to the previous model.
