Nebulae's Mini Pcie Lora-based Concentrator Board - Application: Smart Metering

Nebulae's FCC-certified NM0824-I is an SX1302-based compact size, low-power LoRa concentrator board with 2 x SX1250 & 1 x SX1261 radios with an onboard I2C-based temperature sensor. Compared to the SX1301 LoRaAR chip, it offers higher sensitivity, less power consumption, and a lower operating temperature. It supports SPI-based communication with the host. The advanced fine time-stamped feature helps to identify estimated geo-location. It is designed for M2M and IoT applications and can be widely applied to LoRaWAN gateways. It would be a great choice to reduce technical difficulties and time consumption when developing LoRa Gateway-based system.
