SparkFun LoRa Gateway 1-Channel Hookup Guide

November 15, 2018

How to setup and use the LoRa Gateway 1-Channel in Arduino.
  • Good question - glad you asked! It would be very challenging to remove the cable from the glass of the display, but it is really easy to replace the display module thanks to the FPC connector on the PCB. I'm wondering if you might still be able to use this display though, because the cable is very flexible. There is a short (~1mm) stiffener protruding from the glass but after that the cable can bend more than 90 degress with a pretty small (less than 1mm) radius. I will say if you choose an extreme bend in the cable that it is best not to bend it back and forth too many times. I hope that can help!

  • Thanks!

    Currently Supported:

    The good news is that we have plans for more displays in the future - and that you can add support for past products / other displays. If you're interested in that option let's start a discussion on GitHub!

  • Yep, that should work as long as you are sure that the CS line for the LoRa module is high while you try to access your sensor.

  • Sweeeeeet! Reminds me in a (much more sophisticated way) of the stick sculpture I put together when I was little. I'd love to try this out

  • Hi - good eye. The part used here is the CH340C which has an internal oscillator. This makes it a lot simpler for us to include in designs than the CH340G

  • Woah, those would have have been really helpful, thanks for sharing! I also really like the neat clamper + bendy arm contraption.

  • Awesome, good luck and keep us in the loop about how it goes!

  • Good question. The simple answer is "yes, but we haven't proven it personally." Here's a little more info.

    You'll be able to find a frequency setting function in the majority of the LoRa libraries out there because generally speaking all the LoRa radio modules use the same Semtech SX1276 chip at their core. The RFM95W is one such module so it should have an adjustable frequency range and be compatible with those libraries.

    You can see an example of what I'm talking about in the LMIC Arduino library. The config.h and lmic.h files both have references to both 915 MHz and 868 MHz. Just a little more digging should turn up a function that is used to set the frequency during initialization. It might be as simple as defining #define CFG_eu868 1 instead of #define CFG_us915 1

    We haven't tested the modules at 868 MHz, however, so if you get this working we'd love to hear about it so that we can say definitively in the future that it is proven. Thanks for asking a great question!

  • No, you should be able to do that with little trouble on a breadboard. Hook up your wires in the way that the schematic shows. Then you should be able to follow along with the hookup guide and use all the same software. Cheers!

  • Hi - you are correct this is only the "digitizer" layer. It is a clear glass pane that can sense capacitive loads like fingers but it doesn't have any intrinsic output ability. There's a whole host of cool things you could combine this screen with: Addressable LEDs, RGB matrices, 7" E-paper display, or even a hand-drawn UI that to slide underneath.

No public wish lists :(
