Description

RF chip The SX1278 mainly uses a LoRaTM remote modem for ultra-long-range spread spectrum communication with high anti-interference and minimizes current consumption. With SEMTECH's patented LoRaTM modulation technology, the SX1278 has a high sensitivity of over -148dBm, +18dBm power output, long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRaTM modulation technology has obvious advantages in anti-blocking and selection, and solves the problem that the traditional design scheme can not take into consideration the distance, anti-interference and power consumption at the same time. Ra-01, Ra-02 operating frequency is 410-525MHz

Click "Open Program File", select the Hex firmware of the MCU, and note that the IRC frequency when the user program is running is 22.1184MHz;

After the download is complete, reset the test board again. Plug in the LoRa adapter board. This test requires two test boards, one for transmission and the other for reception. When the module is powered on without any operation, the LoRa module enters the receive mode. When one of the test boards presses one of the buttons, the module enters the send mode, the light on the right side of the module lights up, and the other module is in the receive module. If data is received, the left light flashes.
