Operation Instructions

Power On/Off

Power-on: Press the “BUTTON C” for more than 2 seconds, or wake up via the RTC IRQ signal. After the wake-up signal is triggered, the program must set the HOLD pin (G4) to high (1) to keep the power on, otherwise the device will shut down again.
Power-off: Without external USB power, press “BUTTON C” for more than 6 seconds, or set HOLD (GPIO4)=0 in the program to power off. While USB is connected, pressing “BUTTON C” for more than 6 seconds will turn off the screen and enter sleep mode (not a full power-off).

Power On/Off Differences

Product Name Power On Power Off
StickC-Plus Press reset button (BUTTON C) for at least 2 s Press reset button (BUTTON C) for at least 6 s
StickC-Plus2 Press “BUTTON C” for more than 2 s, or wake via RTC IRQ. After wake-up, set HOLD (G4)=1 in the program to keep power on, otherwise the device will shut down again. Without USB power, press “BUTTON C” for more than 6 s, or set HOLD (GPIO4)=0 in the program to power off. With USB connected, pressing “BUTTON C” for more than 6 s will turn off the screen and enter sleep, but not a full power-off.

Because StickC-Plus2 removes the PMIC AXP192, the power-on/off method differs from previous versions. As mentioned at the beginning of this document, the operation is largely similar, but the supported libraries will differ. Wi-Fi and IR signal strength have both been improved compared to the previous model.
