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.
