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 this presentation I talk about what concurrency actually is, why it matters for Internet of Things applications, and which platforms are best at handling it.

Hey everyone, so I just got some LoRa modules from REYAX to experiment with long range network applications and these things are so cool! So far I've made a long range security alarm, a button to water plants on the other side of my property, and some bridge code to interact with IP and BLE networks. Just thought I'd do a quick video update on this stuff: The module I wrote is part of the Espruino collection now:  https://www.espruino.com/RYLR I got these LoRa devices from REYAX:  https://reyax.com/products/rylr896/ They seem to only sell them on e-bay right now:  RYLR896

This is an IoT development board for the ESP32 that can be programmed using the Arduino IDE , MicroPython , or JavaScript using Espruino .
