Power Button¶

Button Operations

Power On: Press the button until the light turns green, indicating the system is powering on. You can then release the button.
Shutdown: After powering on, press and hold the button for 2 seconds until the light turns purple, then release. When the power button’s light begins to flash purple, the Raspberry Pi will receive a shutdown signal and proceed to shut down. After the shutdown is complete, the Pironman U1 will turn off. If the RTCEN is connected, the Pironman U1 will enter RTC standby mode. If not connected, the Pironman U1 will power off completely. The power button’s light will turn off once the shutdown process is complete.
Power Cut: If you haven’t configured software on the Raspberry Pi, or for other reasons, you can opt for a power cut shutdown. Press and hold the button for 5 seconds and turns red, indicating a direct power cut. Be cautious with this method as it may damage data.

The RGB is a common-cathode RGB. Once the RGB button is connected, the RGB light will display the current status, which includes:

RGB	Status
Green Light	External Power Input Status
Yellow Light	Battery Power Status
Orange Light Cycling from Dim to Bright	Charging
Red Light Flashing	Low Battery (and not charging)
Purple	Long Press 2 Seconds, Soft Shutdown
Red	Long Press 5 Seconds, Hardware Shutdown

Wiring

The button interface is MX1.25 5P. Use the MX1.25 5P reverse cable to connect the button to the Pironman U1 HAT. The button pin definitions are:
