LR62XE LoRa with Power Amplifier Modules

Ver0.90Feb.2021

LoRa Sensor, Beacon Applications

LR62XE LoRa transceiver module uses a Semtech SX1262 sub-GHz radio

transceiver and a Skyworks SKY65313 power amplifier. An u.FL connector is

on-board for external antenna. It is paired with Fanstel BT840F, a Nordic

nRF52840 BLE 5.2 module. The Cortex M4F MCU in BT840F manages

LR62XE through SPI interface. BT840F GPIOs can be used for sensor data

input or control output. Android OS app is available for field set up through

Bluetooth interface.

BT840F + LR62XE pair can be used in LoRaWAN

application. LoRaWan

stacks are not available from Fanstel.

Cloud Connection, LoRa Gateway

The 2nd application example is in a gateway for

connecting to a cloud server(AWS, Microsoft, Google,

Fanstel development server, etc.) through Ethernet, WiFi,

or LTE network.

BLE 5.2 module manages LR62XE through SPI interface.
