*by S***E on Reviewed in the United States on October 30, 2018*

Worked without any problems on my Raspberry Pi 3 B+ and my Windows 10 computer. They can both communicate perfectly with only 2 of these!I have not tried it yet, but I bet it can communicate with regular, in-circuit HC-12 modules!If you want reliable, 2-way, serial IoT for a computer, please buy this module. This is WAY underrated!!!
