LF1357 LoRa gateway/concentrator module
Part list: 1x LoRaWAN gateway Module
LF1357 is a LoRa concentrator card based on SX1301 or SX1308 chipset. Each module support eight(8) programmable Lora parallel demodulation channels, allowing it to receive up to eight LoRa® modulated packets simultaneously. -142.5dBm high sensitivity combines with +27dBm power amplifier yields industry leading link budget making it optimal for applications requiring extended range and robustness.
Features
- Multichannel: Eight(8) programmable Lora parallel demodulation channels.
- SPI Interface: The SPI interface gives access to the configuration register of SX1301 via a synchronous full-duplex protocol.
- Compact size TYP. 44.0 *27.2 *3.0mm (W*L*H)
- Environmentally-friendly RoHS compliant
