Product Description

RAK2245 Pi HAT is the largest of the RAK2245 family, however it offers complete compatibility with the Raspberry Pi 40pin header. Thus it is a perfect solution for a DIY gateway using the Raspberry Pi at its core. This make for a quick to deploy LoRaWAN solution with low cost and stable performance.

As with the other modules in the RAK2245 line, it is based on the Semtech 1301 and dual SX1257/58 front-end chips. It is a full-fledged 8 channel LoRa Concentrator with a number of improvements over the last generation (RAK831) of this product.

Complete documentation of this product can be found on our website documentation page.

  • Integrated Ublox MAX-7Q GPs Module

  • 40pin female header (fully compatible with Raspberry Pi)

  • Redesigned heat sing for better thermal dissipation and reduced thermal noise

Packaging

  • Board Dimensions: 56.0 x 65.0 x 22.0mm
  • Board Weight: Approximately 1.15 oz
  • Package Weight: 0.3kg (0.66lb.)

  • We’re a unable to get the rak2245 working with the Semtech packet forwarder as we do with 831 and 833, have you ever make it work with it ? Does it use another version of the concentrator chip ? Or it must work right out of the box and we just got a defective one ?

    Hello Sir,

    We have tested multiple ones and they work. Please install the latest firmware from the link:
    https://downloads.rakwireless.com/en/LoRa/RAK2245-Pi-HAT/Firmware/

    Let me know if there is any improvement after flashing the firmware.

  • Does the 1PPS signal go to a Pi GPIO pin or just internally to the SX1301? if not is there somewhere to pick up the 1PPS from the GPS with a jumper wire?

    Hello Sir,

    If you check page 7 of the following dociment, I belive pins 3 and 5 on the header are the ones connected to the GPS (I2C). Could those perhaps serve your purpose?

  • What type of antenna is included with the RAK2245? I want to use an outdoor antenna, is the Fiber Glass Antenna - 5.8dBi - N-Type to SMA antenna compatible with the RAK2245?

    Hello Sir,

    The included antenna is an iPEX pigtail. You can use the 5.8dBi antenna, however you will need an iPEX to N-type cable, some make sure you choose this option when ordering your antenna (the connector on the RAK2245 is not SMA, but iPEX).

    Regards

  • When will it be available again? 868 EU version.

    Hello Sir,

    It is back in stock now. Feel free to order.

  • Looking at the PCB of the Pi Hat there is a chip next to the GPIO header - what is it for? I want to wire the Stamp Edition to a Raspberry and wonder if this additional chip is crucial for stable operation.

    Hello Sir,

    This is he EEPROM for the pin mapping. This is indeed crucial if you want to have the proper pinout. If you are going to be wiring it yourself you can go without it, however the pins need to be re-wired in the correct order in order to match the 40pin RPi header.

    Here you have the pinout on the Stam edition (It is for the 96Boards doc, but they are the same)


    https://downloads.rakwireless.com/en/LoRa/RAK2245-96Boards/Hardware-Specification/RAK2245-96Boards_User_Manual_V1.2.pdf

    Here are the additional ones on the side of the board (not the 40 pin header holes)

    https://downloads.rakwireless.com/en/LoRa/RAK2245/Hardware-Specification/RAK2245_User_Manual_V1.2.pdf


    This is the document for the wiring of the PiHat to the Rpi:

    https://downloads.rakwireless.com/en/LoRa/RAK2245/Hardware-Specification/RAK2245_RAK831_Design_Guide_Comparison.pdf

    You simply needd to remap them in accordance with the last document. This can be done software wise in the Raspberry, or hardwarewise via physical connections.
    It is some work, but you know best what your application wyou want to sue it for so choosing the Stamp is perhaps best (I would go with the Pi HAT cause I am lazy;))

    I hope this helps

  • Would this Gateway work in the new Raspberry PI 4?

    Hello Sir,

    If you mean the RAK2245 Concentrator module, yet it will work with Any raspberry Pi as they all have the same 40 pin GPIÖ header.

  • I followed Get Start with RAK2245 6 RAK831 RPI LoRa Gatewa Version V1.0 | May 2019 and tried to access the gateway through SSH (PuTTY) and get network error: Connection refused. On my Raspberry Pi screen I need the password for iotloragateway login Any help?

    Hello Sir,

    Did you connect to the Gateway via wi-Fi AP? Did you use the 192.168.12.1 IP Address? The username is "pi", password "raspberry".

    Those are all in the manual? As I saw you replied via email and you still ahd no luck, what firmwre version was the one you flashed as instructed in the manual you mentioned to have used for configuring the device?

    Regards
    Vladislav

  • Does this unit didn't have any antenna accessories on it? if not , do you have antenna connector from microFl to sma connector?

    Dear Sir/Madam,

    The RAK2245 Pi HAT edition comes with a LoRa and GPS antenna in the box. If yours we missing please let me know. If you want an iPEX to SMA cable you can order one here: https://store.rakwireless.com/products/ipex-to-sma-connector   Regards
