Dev Board with Lora, MC and Battery Connection

Projects General Guidance

Hi. I'm trying to find a dev board with a microcontroller, serial connection, integrated LoRa module and a battery connection (to run it standalone). I found some but quite expensive (u$d 100). Do you know any affordable option for prototyping?
Thanks very much.

+1, Those Heltec boards are very reasonable.

For the case shown in the link there is a clip on battery holder available to which you can fit a 102040 Lithium battery and switch.

Apart from the Heltec boards, Lilygo make a range of LoRa boards as well, their LilyGo T3 V1.6.1 is reasonably priced too.

I saw the HiLetgo first, about the same price..
but they were not soldered..
I like to buy them soldered from the factory..
I have used Lilygo before, idk, i tend to find them all working..
