LR62E LoRa Module Product Specifications

Ver0.90Jan.2020

LoRa Sensor, Beacon Applications

LR62E LoRa transceiver module uses a Semtech SX1262 sub-GHz radio transceiver. An u.FL

connector is on-board for external antenna. It is paired with Fanstel BM833, a low cost Nordic

nRF52833 BLE 5.1 module. The Cortex M4F MCU in BM833 manages LR62E through SPI

interface. BM833 GPIOs can be used for sensor data input or control output. Android OS app is

available for field set up through Bluetooth interface.

BM833 + LR62E 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 cloud servers(AWS, Microsoft,

Google, Fanstel development server, etc.)

through Ethernet, WiFi, or LTE network.

LR62E LoRa Module Product Specifications Ver 0.90 Jan. 2020 for Battery Power Application Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal and 2 capacitors as shown in the upper left corner of the evaluation board schematics. The 32MHz main clock won’t be active at idle state to save power. Two inductors required for DCDC converter are inside BM833 module. You can enable DCDC to lower power consumption.
