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.
