Hi all.
I want to use LoRa in 433MHz, using LoRaWan.
I search and find out RA-02 That based on SX1278.
-
Is there any LoRa chip that including MCU so I will not need to buy separate MCU and connect to LoRa using SPI?
-
What is the difference between SX126x and SX1278? For using LoRaWan ,low power consumption and Long range?
Thank you.
