The Heltec Vision Master E290 is another E-Paper mesh node, capable of displaying messages and acting as a full-fledged ChatterBox node or as an anonymous / unaddressed node.
A DS3231 realtime clock and/or DFR1103 GPS is required for accurate time acquisition.
As you can see, the display is extremely clear and easy to read. The only downsides versus a T3S3 are there’s not a hard on/off switch and the SMA connector uses a pigtail, which isn’t quite as good as the T3S3 mesh node‘s soldered SMA connector.
The case shown here is one designed by HarukiToreda which you can download from here.
