RAK833 SPI and USB Gateway Concentrator for LoRa® mPCIe Module (based on SX1301 and FT2232H)

The RAKwireless RAK83-SPI/USB 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.

RAK833-SPI/USB

Target for development & femtocell gateways

• Supports both SPI and USB interface
• Includes FT3323H chips
• USB interface allows for easy integration with a lot of different controller boards in the development stage.
• With the USB port, you can easily access information of I2C, SPI, serials, and can do better troubleshooting.
• Without the FTDI, if any troubleshoot is needed then you have to go by soldering and can put the PCB in danger.

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/USB

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

Supports SPI and USB interface

RAK833 refer Semtech's reference design of SX1301, add a 4 channel SPDT to switch SPI of SX1301 to PCI edge connector or FT2232H which coverts SPI to USB2.0 interface

An SPI interface is provided on the PCIe_SCK, PCIe_MISO, PCIe_MOSI, PCIe_CSN 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.

Supports high speed USB to SPI by FT2232H, it includes a high-speed USB2.0 compliant interface with maximum 480Mb/s data rate, representing the interface for any communication with an external host application processor. The module itself acts as a USB device and can be connected to any USB host equipped with compatible drivers. For more information, please refer to the data sheet of FT2232H.
