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.
