RAK2245 RPi HAT Edition (Pre Order)
The RAK2245 RPi HAT Edition is a professional-grade LoRaWAN gateway module designed for Raspberry Pi integration, enabling long-range wireless communication up to 15 km in open space with low power consumption. IoT developers, smart city integrators, and industrial automation engineers use this module to build scalable LoRaWAN networks for remote sensor monitoring, asset tracking, and distributed data collection applications. This product solves the critical challenge of extending wireless connectivity beyond WiFi and cellular limitations while maintaining cost-effectiveness and minimal power draw for battery-operated deployments.
Product Overview
The RAK2245 RPi HAT Edition operates as a concentrator module that interfaces directly with Raspberry Pi through the GPIO header, converting the Pi into a fully functional LoRaWAN gateway. The module features a Semtech SX1301 baseband processor with dual SX1257 RF front-ends, enabling simultaneous reception of up to 8 LoRa channels plus 1 FSK channel. This architecture allows the gateway to handle multiple concurrent transmissions without packet loss, making it ideal for dense IoT deployments. The HAT form factor ensures plug-and-play installation without additional wiring, while the integrated antenna connector supports both internal and external antenna configurations for optimized coverage patterns.
What distinguishes the RAK2245 from competing solutions is its industrial-grade reliability combined with hobbyist accessibility. The module operates across extended temperature ranges (-30°C to +60°C), includes built-in ESD protection, and features redundant power supply paths to ensure continuous operation during power fluctuations. The Raspberry Pi integration eliminates the need for separate gateway hardware, reducing total system cost by 40-60% compared to standalone commercial gateways. Pre-order availability ensures you secure this next-generation module before widespread market adoption, with firmware support for both TTN (The Things Network) and private LoRaWAN server implementations.

How to Use
Installation of the RAK2245 RPi HAT Edition begins with ensuring your Raspberry Pi is powered off and the GPIO pins are accessible. Carefully align the 40-pin header on the RAK2245 module with the corresponding GPIO pins on your Raspberry Pi (Pin 1 at the corner), then press firmly until the module sits flush against the board. Connect an antenna to the SMA connector on the module, then power on your Raspberry Pi. The module will automatically initialize and appear as a serial device at /dev/ttyAMA0 with default baud rate 115200. Install the RAK gateway firmware using the provided SD card image or download the latest version from RAKwireless GitHub repository, which includes pre-configured packet forwarder software compatible with TTN and Chirpstack LoRaWAN servers.
Configuration requires editing the global_conf.json file to specify your gateway location (latitude/longitude), frequency band matching your region, and server connection details. For TTN integration, register your gateway using the unique EUI printed on the module label, then configure the packet forwarder to connect to your regional TTN server (eu1.cloud.thethings.network for Europe, au1 for Australia, etc.). The module requires stable 5V power supply capable of delivering 500 mA during peak transmission periods; use quality USB power supplies or regulated 5V battery packs to prevent brownouts. Monitor gateway health through the built-in web interface accessible at your Raspberry Pi's IP address, which displays real-time packet statistics, RF performance metrics, and connected device information. For optimal performance, mount the antenna 2-3 meters above ground level with clear line-of-sight to the sky, avoiding metal structures and dense foliage that attenuate LoRa signals.
Frequently Asked Questions
What is the difference between RAK2245 and RAK2287 models?
The RAK2245 RPi HAT Edition uses Semtech SX1301 concentrator optimized for Raspberry Pi integration with lower cost, while RAK2287 features newer SX1302 processor with improved performance and power efficiency. RAK2245 is ideal for budget-conscious deployments and educational projects, whereas RAK2287 suits high-volume commercial gateways. Both support identical LoRaWAN protocols and frequency bands, making them interchangeable for most applications.
Can I connect multiple RAK2245 modules to a single Raspberry Pi?
No, the RAK2245 HAT occupies the entire 40-pin GPIO header and uses dedicated SPI communication lines. However, you can deploy multiple Raspberry Pi boards with individual RAK2245 modules in a mesh topology, where each gateway connects to your LoRaWAN server independently. This approach actually improves coverage and redundancy compared to a single gateway, as overlapping reception areas reduce packet loss through spatial diversity.
What antenna should I use for maximum range and coverage?
For general-purpose deployments, use a 5 dBi omnidirectional antenna mounted vertically 2-3 meters above ground, which provides balanced 360-degree coverage up to 15 km in line-of-sight conditions. For directional coverage (e.g., monitoring a specific valley or corridor), upgrade to 9 dBi Yagi antenna pointing toward target area. Avoid antenna placement near metal objects, water bodies, and dense vegetation, as these attenuate LoRa signals by 6-12 dB. For indoor deployment, use a 2 dBi internal antenna, accepting 40-50% range reduction in exchange for weatherproofing.
Is the RAK2245 compatible with The Things Network (TTN)?
Yes, the RAK2245 is fully compatible with TTN and pre-configured with TTN packet forwarder software. Simply register your gateway on TTN console using the Gateway EUI, configure the correct frequency band for your region, and the module automatically connects to your nearest TTN server. TTN provides free backend infrastructure for up to 10 million messages monthly, making it ideal for hobbyist and small-scale IoT projects.
What power supply specifications do I need?
The RAK2245 requires stable 5V DC power supply capable of delivering minimum 500 mA continuous current, with peak current reaching 800 mA during simultaneous LoRa transmissions. Use quality USB power supplies rated for 2.5A minimum, or regulated 5V battery packs with 3000+ mAh capacity. Avoid cheap USB chargers and low-quality power banks, as voltage fluctuations cause module resets and packet loss. For outdoor installations, use industrial-grade 5V power supplies with wide input voltage range (9-24V) and built-in surge protection.
