Screen ​

The RH2 features a 2.13" monochrome e-ink display with a resolution of 250x122 pixels, which is visible in direct sunlight and has a very low power consumption.

The default firmware of the RH2 has a simple user interface that makes use of the screen to display information such as GNSS status, battery level, and allow basic control of the device.

The screen can also be used by the ESP32 microcontroller as part of a custom application, for example to display sensor data, custom menus, alerts, messaging and more.

Defaults ​

The default firmware has a single main home screen, with a sub menu screen.

Home ​

The home screen shows basic device status, and basic device control.

The status bar at the top shows:

  • SIM status
  • GSM status and signal strength
  • Battery level
  • Charge state

Disarmed ​

A device would normally start in a disarmed state.

In this state the device is not attempting to get a GNSS fix or report its location, or connect to GSM.

The center button can be used to arm the device (See armed below).

Or the menu button can be used to access the menu below.

The actions selection currently does nothing, and is intended for future use.

Armed ​

When armed the device will find it location using GNSS, and report it to the Lightbug Cloud, then streaming RTK corrections if available for the device.

Information above the status of this process will be shown on the screen.

The menu allows selection of:

  • Base station mode (allowing the device to work as an RTK base station)
  • 1Hz RTK tracking
  • 2Hz RTK tracking
  • 5Hz RTK tracking
  • Displays the Device ID

Custom ​

Custom applications running on the ESP32 can make use of Toit SDK and or device API to draw custom screens.
