2AF6B-5167WisLink Module

RAK5167 WisLink LPWAN Concentrator Datasheet Overview Product Description The RAK5167 is an LPWAN Concentrator Module with PCI Express M.2 Type 2280 form factor and Key B-M Dual Key IDs based on Semtech SX1303 and SX126X for Listen Before Talk feature, which enables easy integration into an existing router or other network equipment with LPWAN Gateway capabilities. It can be used in any embedded platform offering a free PCIe M.2 slot with a USB connection. Furthermore, the ZOE- M8Q GPS chip is integrated onboard. This module is an exceptional, complete, and cost-efficient gateway solution offering up to 10 programmable parallel demodulation paths, 8 x 8 channel LoRa packet detectors, 8 x SF5-SF12 LoRa demodulators, and 8 x SF5-SF10 LoRa demodulators. It is capable of detecting an uninterrupted combination of packets at 8 different spreading factors and 10 channels with continuous demodulation of up to 16 packets. This product is best for smart metering fixed networks and Internet-of-Things (IoT) applications.

It also presents the block diagram that discusses how the board works. Board Overview RAK5167 is a compact LPWAN Gateway Module, making it suitable for integration in systems where mass and size constraints are essential. It has been designed with the PCI Express M.2 Type 2280 form factor in mind, so it can easily become a part of products that comply with the standard, where they allow cards with a thickness of at least 3.7 mm. The board has two MHF4 IPEX connectors for the LoRa and GNSS antennas and a standard 75-pin connector (M.2) with Key B-M Dual Key IDs. Block Diagram The RAK5167 concentrator is equipped with one SX1303 chip and two SX1250. The first chip is utilized for the RF signal and the core of the device, while the latter provides the related LoRa modem and processing functionalities. Additional signal conditioning circuitry is implemented for PCI Express M.2 compliance, and two MHF4 IPEX connectors are available for external antenna integration. Hardware The hardware is categorized into seven (7) parts. It discusses the interfacing, pinouts, and their corresponding functions and diagrams. It also covers the parameters and standard values of the board. Interfaces • Power Supply - The RAK5167 concentrator module must be supplied through the 3.3Vaux pins by a DC power supply. The voltage needs to be stable since the current drawn can vary significantly during operation based on the power consumption profile of the SX1303 chip (for more information, see the SX1303 Datasheet). • USB Interface - The USB interface mainly provides for the USB_D+, USB_D- pins of the system connector. The USB interface gives access to the configuration register of SX1303 via an MCU STM32L412KBU6. Only the slave side is implemented. • UART and I2C Interface - RAK5167 integrates a ZOE-M8Q GPS module which has UART and I2C interface. The PINs on the golden finger provide a UART connection and an I2C connection, which allows direct access to the GPS module. The PPS signal is not only connected to SX1303 internally but also connected to the golden finger which can be used by the host board. • GPS_PPS - RAK5167 reserved the GPS_PPS input for received packets time-stamped and Fine timestamp. • MCU RESET - RAK5167 USB card includes the RESET active-low input signal to reset the MCU. SX1303’s RESET is controlled by MCU to reset the radio operations as specified by the SX1303 Specification. • Antenna RF Interface - The module has two RF interfaces over a standard MHF4 IPEX connector with a characteristic impedance of 50 Ω. The RF port (J1) supports both Tx and Rx, providing the antenna interface for LoRa. The RF port (J2) provides the antenna interface for GPS.
