PanelPilot | SGD 21-B

2.1" E-paper Dot Matrix Display


Lascar's SGD 21-B is a low cost, ultra low power, sunlight readable, single channel voltmeter with a sleek monochrome e-paper dot matrix display.  Using Lascar’s simple PanelPilot B software platform, choose from a selection of six analogue and digital voltmeter apps and customisable labels, scaling and alarms for your own specific application.


The display works with free PanelPilot B configuration software (available for Windows 7, 8 and 10) providing six analogue and digital voltmeter Apps which can then be customised to suit individual applications.  Elements of each configuration that can be changed in the software include:

  • Custom labels
  • Scaling
  • Two alarms
  • Colour inversion
  • A picture or logo can be added to the display on power-up.

For an overview of the software, see our SGD 21-B Setup video tutorial.

Once the App is complete, upload it to the SGD 21-B display using CABLE USB A-SIL5 (Not Included). The panel or enclosure installation of the display is easy, simply use the panel fixing clip to mount the display.

Lascar’s PanelPilot B software is available for download free of charge.
