RAK2287 1 Overview 1.1 Introduction RAK2287 is a LoRa concentrator card with mini-PCIe form factor based on SX1302, which enables an easy integration into an existing router or other network equipment with LoRa Gateway capabilities. It can be used in any embedded platform offering a free mini-PCIe slot with SPI or USB connection. Furthermore, ZOE-M8Q GPS chip is integrated on board.
RAK2287 1.3 Package Contents Figure 1 | RAK2287 board 2 WisLink LoRa Module RAK2287 2.1 Overview The board only weighs 9.7 grams, its length is 50.95 mm while its width is 30 mm. The 4 board width, top-side and bottom-side keep-out areas and all other dimension is defined by PCI Express Mini Card Electromechanical Specification except for the card thickness (nominal value of 3.7 mm).
RAK2287 2.2 Block Diagram RAK2287 card integrates one ZOE-M8Q, one SX1302 chip and two SX1250 chips which represent the core of the device. This provides the related LoRa modem and processing functionalities. Additional signal conditioning circuitry is implemented for PCI Express Mini Card compliance, and two UFL connectors are available for external antennas integration. 5 Figure 3 | RAK2287Block Diagram 2.
