Lora Module SX1278 868MHz Lora Data Module 800mW 5km data
transmitter UART
LS-LR1000 provide RS232, RS485 or TTL interface, please choose one
when you place order.
General Introduction
LS-LR1000 is a wireless serial port module, operates at 433MHz
default (or 868MHz/915MHz), default 16 channels. It uses
SX1278/SX1276 chip from Semtech, supports transparent data
transmission. LS-LR1000 adopts LORA spread spectrum technology. Its
transmission distance is longer than conventional radio. FEC
algorithm technology ensures LS-LR1000 has high coding efficiency
and good correction performances.
