Description The RAK5146 PiHAT Kit is a Raspberry Pi-ready LoRaWAN gateway development kit built around a RAK5146 SPI concentrator module and a RAK5146/RAK2287 Pi HAT. The concentrator uses Semtech's SX1303 baseband processor and fits projects that need a compact, cost-effective way to prototype or deploy a multi-channel LoRaWAN gateway. This RAK5146 PiHAT Kit is the With GPS / EU868 configuration. It includes the GPS version of the SPI concentrator, the EU868 regional band, a Pi HAT adapter for the Raspberry Pi 40-pin header, LoRa and GPS antennas, and mounting hardware for a clean gateway assembly. Notice: Helium is not accepting these gateways into the blockchain because the Alpha Hotspot program has ceased. If the project goal is to actively participate in the Helium network and earn HNT, choose a RAK Hotspot V2 or another compatible Helium hotspot instead. Features RAK5146 PiHAT Kit configured with GPS and the EU868 regional frequency band. RAK5146 SPI concentrator module based on the Semtech SX1303 LoRa core. Built-in ZOE-M8Q GPS module for gateway positioning and timing support. RAK5146/RAK2287 Pi HAT adapts the SPI mini PCIe concentrator to Raspberry Pi 40-pin GPIO. Compatible with Raspberry Pi 3 Model B+ and Raspberry Pi 4 through the Pi HAT form factor. Supports up to 10 programmable parallel demodulation paths and LoRaWAN gateway packet detection. Includes LoRa and GPS antennas plus mounting hardware for faster gateway assembly.

Product List 1 RAK5146 SPI module 1 RAK5146/RAK2287 PiHAT 1 MHF LoRa antenna 1 MHF GPS antenna for the selected GPS configuration 1 Spacers and nuts kit for secure PiHAT mounting on the SBC Other Content The RAK5146 PiHAT Kit is intended for Raspberry Pi gateway builds that use an SPI concentrator. The Pi HAT routes SPI signals from the Raspberry Pi 40-pin header to the mini PCIe concentrator module and also exposes GPS-related UART, reset, and standby connections described in the Pi HAT documentation. Before powering a RAK5146 PiHAT Kit gateway assembly, install the LoRa and GPS antennas. Operating gateway radio hardware without the required antennas can damage the boards. For software setup, RAK documentation describes flashing gateway firmware, accessing the gateway through Wi-Fi AP mode or Ethernet, enabling SPI on Raspberry Pi, and installing the RAK common gateway stack.
