2PCS LoRa Evaluate Board for 22dBm 160mW LoRa2021 Wireless LoRa Module with LR2021 Chip SPI Module 915MHz

2PCS LoRa Evaluate Board for 22dBm 160mW LoRa2021 Wireless LoRa Module with LR2021 Chip SPI Module 915MHz Popis

LoRa2021 SPI module using LR2021 chip , Max: 22dBm, support S band for satellite application
With normal power supply, toggle the power to turn the device. The LCD screen the demo board will display the "Setting" interface. Briefly press the or DOWN key to move the cursor
When the cursor is the parameter you to modify, press the SET key briefly to make the cursor flash. Then, use the or DOWN key to adjust the parameter. Press the SET key again to confirm the modification
To enter the test function corresponding to the "Mode" parameter, long-press the SET key.Briefly press the SET key to return to the "Setting" interface

Function Description
The LoRa2021 wireless module demo board primarily implements bidirectional communication
(Master and Slave) in LoRa mode, along with sleep (Sleep), transmit power (TxTest), and
receiver sensitivity (RxTest) testing functions at the modulations of FLRC and LoRa.
Note: Transmit power and receiver sensitivity must be tested with instruments.
Prepare two LoRa2021 demo boards, and select the modulation: LoRa or FLRC. Set one to Master mode as the communication host, and the other to Slave mode as the communication slave. (Set the LoRa or FLRC communication parameters: FREQ, SF, BW, and CR to be the same; otherwise, communication will fail.) the communication interface screen, the Tx_cnt and Rx_cnt values will keep increasing. (The red indicator light represents a successful transmission, and the indicator light represents a successful reception.)
