The RAKwireless RAK83-SPI is a complete and cost effective LoRa 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.



Target for commercial production

  • SPI is in Semtech reference design for carrier grade gateways
  • Proven stable performance
  • Mandertory interface for gateway targeted for larger traffic amounts

LoRa Gateway Frequency Band

  • 433 (433MHz - 435MHz)
  • 470 (RX: 470MHz - 490MHz)(TX: 490MHz - 520MHz)
  • EU 868 (865MHz - 872MHz)
  • AS 923 (923MHz - 925MHz)
  • AU 915 (915MHz - 928MHz)
  • US 915 (902MHz - 928MHz)

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. 

Product Specification

  • Frequency band 868MHz & 915MHz
