This Lora relay helps to extend the Lora networks to control actuators/ lights/ motors, to create automatic applications such as farming, aquaculture, and pasture.
There 4 channels of the relay on the board, with max current 10A@277V AC. The main controller Atmega328P is Arduino Uno bootloader pre-loaded, which allows the users to program it with Arduino IDE directly. There also the Lora Relay 30A for higher power applications.
Makerfabs CP2104 USB to Serial Converter Arduino Programmer is strongly suggested for re-programming:
