Product Description

LR-101H is a low power-consuming, half-duplex module. It can wirelessly transmit data

to long-distance. It is built-in high-speed and low power-consuming MCU and SX1276

modulation chipset. This chipset is applied with the forward error correction technique

which greatly improves interference immunity and advances sensitivity. The coding

can detect errors and automatically filter out errors and false data

LR-101H provides multi-channels. It supports various settings like baud rate,

transmission power, and transmission speed, etc.

LR-101H is suitable for long-distance transmission or harsh environments.

Product feature

 Ultra-high sensitive receiving ability by LoRa spread spectrum modulation

technology

 Long-distance transmission (1kM)

 Support setting various parameters like baud rate, transmission power, and

transmission speed

 Multi-channel, dual data buffer (each 256 Bytes)

 Instant wake up over the air

 Four operating modes

 Built- in watchdog

 PIN connector for easy development and test
