- RGB LED (shows colorized status)
- Button (short press: flip display page / long press: send alarm message)
- Silicon unique ID
- Battery voltage monitoring (analog read / AXP192 / IP5306)
- GPS (Generic serial NMEA, or Quectel L76 I2C)
- Environmental sensors (Bosch BMP180/BME280/BME680 I2C; SDS011 serial)
