EBYTE E32-915T20D, SX1276 915MHz 100mW DIP Wireless Module

You can get this unit from Amazon but I am not recommending to get this unit at least for now because I do not have good confidence on this unit yet.

I haven't yet thoroughly verified whether this unit is working or not but I am coding now ...
