Thanks for doing this series, Chris. It’s been very helpful as well as timely for me, as I’m looking to build a project around a cellular module soon, also with an nrf52.
One question, though:
I can’t seem to find anywhere to actually buy EG91/BG95s. At least none of the usual suspects, nor octopart have orderable parts. I’ve found a few sketchy options, with fairly high prices…
I was also considering the nRF9160, and I can find that everywhere, for ~19-20 or about half of the best price I could find the Quectel options. It looks like it would be a great combo part for one of the cheaper nrf52 parts too, and since it is also from Nordic, you’d be able to use the same SDK with both chips.
Did you consider the nRF9160 and decide against it for cost or other reason(s)? Is the Quectel part available for less somewhere that I don’t know about?
