T-BeamSUPREME Meshtastic ESP32-S3 TTGO Development Board LoRa L76K GPS WiFi Bluetooth Module with 1.3inch SH1106 OLED (L76K 868Mhz)

Bought this to use as a Meshtastic node. Working very well in its new 3D printed case.

I have spent countless hours working with these in building mesh firmware for T-Deck, T-Beam supreme, and other devices. These T-Beam supremes are my go-to for mobile nodes, tracker nodes, and base stations.For my home base station, I have one of these combined with a 48" signal plus antenna and a 1 watt amp from sunhaus. Wow...is all I can say. My T-Deck plus, with internal antenna, can get a signal from 6 miles away to the T-Beam with this setup.L76k and ublox are both good. Supposedly I think ublox uses a little less power, but I'm getting >24 hour battery life with a cheap rechargeable using either. I leave mine plugged in or on solar constantly though.The real-time clock is something that's missing from most similar devices, and it's quite important for security purposes, and not being dependent on GPS for time.This has an SD card reader, which is required for my firmware (storing encrypted packets, public keys, etc). I'm not sure how other mesh systems get by with just flash, id expect wear leveling, but I use the SD extensively.The LoRa radio works flawlessly, as does the WiFi. I don't use BLE for my system, so I can't speak to thatMy base station has been running for months.I don't know how well other systems work with it, but it is really a fantastic fit for ChatterBox.Highly recommend!

This unit had problems getting the internal GPS active. after some fiddling with settings and disconnecting and reconnecting the GPS antenna connector several times it sprang to life. Now it works well, but battery time is limited. The ESP32 units are power hungry.

Both of mine have functioned flawlessly for weeks. A little pricey, but they do what theyre supposed to do

Arrived fresh of the boat. Testing 1-2-3. 3-2-1

Still figuring it all out but the device appears to work.
