RAK833 SPI Gateway Concentrator mPCIe Module for LoRa® (based on SX1301)

The RAKwireless RAK83-SPI is a complete and cost effective gateway solution offering up to 10 programmable parallel demodulation paths. It's perfect for smart metering fixed networks and IoT applications with up to 500 nodes per Km2 in moderately interfered environments.

The modules have the industry standard PCI Express Mini Card form factor, which enables easy integration into an application board.

Where to use RAK833-SPI

• Industrial router
• IoT Gateway
• VPN Router
• Industrial computer

Supports SPI

RAK833 refer Semtech's reference design of SX1301, communicates with host through SPI transfer interface.

An SPI interface is provided on the PCIe_SCK, PCIe_MISO, PCIe_MOSI, PCIe_CSN, PCIe_RST (Reset) pins of the system connector. 

The SPI interface gives access to the configuration register of SX1301 via a synchronous full-duplex protocol. Only the slave side is implemented.
