MicroPython and LoRa

Will AdaFruit be stocking the PyCom LoPy?

If not what combination of AdaFruit MicroPython board / Feather / backpacks are
the nearest equivalent of the LoPy?

I would go with Adafruit products if equivalent in features / function / cost and ease of use.

Try an ESP8266 based Huzzah, either #2821 or #2471, put it onto a piece of perfboard, and add in any of the LoRa radio breakouts (#3072, 915Mhz if you live in the United States). These take an SPI comm link to the microcontroller, so 3-4 wires connecting them. They might be better connected to real SPI hardware pins on the ESP, but I doubt it makes much difference (it's very fast) and bit-banging SPI pins is pretty painless. That will give you a uPython MCU + Wifi + LoRa.

When there's better support for bluetooth, you might be able to switch out the ESP8266 breakout for an ESP32 board, but hey, that doesn't commercially exist quite yet from what I can tell.

This won't give you a driver ("lora.py"), but I think writing that might be the fun part. If this hasn't been written by *somebody* yet, I'd be surprised.
