The 433MHz frequency makes this great device for use with TinyGS project.

I requested that Rokland carry the 433MHz version of this device so that I could use it with the TinyGS project ( The satellites that TinyGS receives transmissions from use the 433MHz band instead of the US Lora 866MHz frequency, so you cannot use the US version of the T-Beam for that purpose.

This device has worked well for the 11 months I have used it. The images displayed on the TinyGS screen are regularly changed, so the screen does not burn in as it has on my Meshtastic T-Beams.

This would be a fun project for teens to adults.
