A product that I have not yet seen mentioned here has popped up in a search on banggood:
2x LILYGO TTGO ESP32 Lora modules with a case for $60. No GPS but it supports an optional Lithium Poly Battery.
A comment says that the case is 3d printed. Other than the device being made by @Syed, this looks to be an easy turn key option if you don’t need water or dust resistance.
I don’t have nor endorse this product but I’d bet that this is the tlora-v1 that we already have binaries for. Anyone here have one?
