The LR1268 module is designed based on SX1268. SX1268 sub-GHz radio transceivers are ideal for long-range wireless applications. These devices support LoRa® modulation for LPWAN use cases and (G) FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements utilizing the global LoRaWAN® standard or proprietary protocols.
The devices are designed to comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance™.
The radio is suitable for systems targeting compliance with radio regulations including but not limited to China regulatory requirements and ETSI EN 300 220 (434 MHz). Continuous frequency coverage from 410 MHz to 810 MHz allows the support of the 490 and 780 MHz Chinese low-power short-range device bands.
