LoRa1280F27/LoRa1281F27 2.4GHz 500mW 27dBm LoRa Chip RF Wireless Transceiver Module For RC Airplane

LoRa1280F27/LoRa1281F27 module integrate with Semtech's high performance rf chip sx1280/1281, with external PA,has 500mW(27dBm) output power. It adopt 2.4GHz frequency and Lora modulation, which has better receiving sensitivity and anti-interferance.

Note : Only Lora1280F27 has the funtion of distance measurement.

Features

Frequency Range: 2400-2500MHz

Maximum power output: 27dBm

Data rate: @LoRa=0.476-202Kbps

Sensitivity up to: -132dBm@loRa

LoRa Modulation

Packet mode FIFO: 256 Bytes

Operating voltage range:2.0-5.5 V

Operating temperature range: -40 ~ +85 °C

Difference between 1280&1281

1280 chip is able to measure the distance ,but 1281 isn't.
