Operating Instructions for Powering On and Off

Power On:

  • The device can be powered on in two ways:
  • By pressing the "WAKE" button.
  • By an IRQ signal triggered by the RTC timer.
  • After activating the wakeup signal, it is necessary to set the Hold(G46)-Pin high (1) during program initialization to ensure power supply. Otherwise, the device will automatically return to sleep mode.

Power Off:

  • The device can be powered off if there is no external USB power supply:
  • By pressing the RST button.
  • By setting HOLD(GPIO46)=0 in the program to completely power off the device.


  • Equipped with a 1.14-inch ST7789 color display
  • Powered by the powerful ESP32-S3 microcontroller
  • Integrated rotary encoder for precise inputs
  • Supports a wide input voltage range from 6 to 36V DC
  • Multiple operating modes: USB, DC, or battery
  • Programmable with Arduino and UIFlow, providing flexible development options
  • Fits into standard 1/32 DIN enclosures

Application Examples:

  • Use in smart home systems for monitoring and control of devices
  • Application in industrial automation projects
