RHF76-052 LoRaWAN Module
Low Power Small Size High integrated LoRaWAN Module
General description
RHF76-052 LoRaWAN Module is a low
cost, low power and small size module,
embedded with Semtech’s LoRa
propriety chip SX1276 and ST’s ultra-
low power MCU STM32L051/052xx.
The module designed by Ai-Thinker
(Shenzhen) is targeted to application in
sensor networking and others IOT
device powered by battery which need
low power consumption to extend the
battery lifetime.
This datasheet will give some details of
description of the module, including
HW design info, performance validation,
and application information.
