This involves 2 pieces of h/w.
The HAT is primarily for a Pi Zero, but it works with any Raspberry Pi with 40 GPIO pins, hence my Pi 1 B+ qualifies.
I’ve had this Pi for years now and it was gathering dust. So recently decided to pick it up and do something with it. First I set up a Pi-hole instance on it and then a Telegraf+Influxdb+Grafana instance to monitor my home Internet connection. Then found that I also had a BBC Micro:bit lying around and it comes with a bunch of sensors built in. So thought if I could connect the Micro:bit with the RPi, then I could use the sensors to monitor my home temperature real time for example. The other option is to get a temperature sensor for the Pi. But let’s call that plan B.
