Looks nice for some uses, but pretty big for a dog collar, almost 3" on a side. I've some long/thin dev boards that I could pair with an 18650 that should be closer to 1".
I'm planning to use a small LiPo battery with a JST connector. The whole footprint should be slightly larger than 3x4x1 cm. Still a bit too large for a pocket device, but perfect for a collar.
Sounds great, best I found so far is the RAK19007 (30x60mm), then add a GPS (RAK12500). It will be kind of long (60mm + case) but not too wide (30mm + 3d printed case).
Or the Mesh Node T114 Development Board V2 (23mm wide).
