I got a handful of LoRa modules from Reyax a while back, the RYLR896 model based on Semtech SX1276 chips. Instead of using an SPI interface they operate over UART using a small set of AT commands. This made them easier to work with since I didn't have to dig too deeply into a bunch of SPI registers and Semtech specs and they communicate between one another really well. My Espruino JS module for them is available here , which I've used in a few of my YouTube videos. And more recently I've written a MicroPython module for them here . (A pair of Reyax RYLR896 modules) But, always being on the lookout for different boards and platforms I eventually ended up with a few Maduino LoRa boards. These are cool because they have an Arduino-compatible ATmega328 and the same Semtech LoRa chip (via an RFM95) both integrated on one board. They weren't compatible with Espruino or MicroPython though, and they used the SPI interface instead of AT commands so I knew I would need to lo...
In today's video I be built a solar powered LoRa signal repeater to extend the range of my LoRa network. This can easily be used as the basis for a LoRa mesh network with a bit of extra code and additional repeaters. Even if you're not into LoRa networks all of the solar power hardware in this video can be used for any off-the-grid electronics projects or IoT nodes!
