ThinkNode M5 Meshtastic™ Radio

It's a handy little unit. Battery life seems to vary from day to day, running most of the day sometimes and other days for only a few hours, and I don't know what's different (GPS remains on). It shipped with a small lanyard but no instructions on how it attaches to the radio. I think I finally figured it out, removing the antenna and placing the small plastic loop around the SMA connector and replacing the antenna. It came flashed with Meshtastic at my request, but I've since switched to Meshcore.

Great Little Beast!! Meshtastic Radio’s has a New Family Member! So Powerful and a Tool!

A great little piece of kit. The battery lasts for multiple days!
