LoRa1280 is a 2.4G wireless transceiver module. This module uses SX1280 from Semtech. It is a LoRa modulation with maximum 12.5dBm output power. This wireless module has good sensitivity and good anti-interference. Also Lora1280 can measure the range between the transmitter and receiver.

The wireless module of LORA1280 series is our main product series. The core chip adopts Semtech's SX1280 RF chip, which uses the lora modulation mode, works in the 2.4GH frequency band, and has the ranging function. It has a good receiving sensitivity and anti-interference ability.

DEMO Board function

The SX1280 wireless module ranging demo board mainly implements the RX demonstration function of the SX1280 and the two-way communication in the LoRa mode.

The parameters of the two modes in the ranging demo board can be modified.

With our sample program, it is convenient to observe the SPI communication between the MCU and the wireless module, and use this development board as a standard signal source without professional RF instruments, debug the customer's development program, and greatly shorten the software engineer's Product development cycle.

Operating mode

1.The ranging demo board has two main functions: the ranging demonstration function and the two-way communication in the LoRa mode.

2.Ranging demonstration function- After selecting the ranging mode interface from the main interface, set the ranging mode parameters to be consistent, and then set the master-slave to measure the distance.

3.Communication test function in LoRa mode- After selecting the LoRa mode interface from the main interface, set the LoRa mode parameters to be consistent, and then select the LoRa communication interface to test.

Main interface

Button Features There are three buttons on the demo board, which are SET button, UP button ,and DOWN button; the function is as follows:
