[coverclock]

I do embedded, real-time and distributed product development for clients in the commercial, enterprise, aviation, defense, and big science domains. I probably own two dozen Pis of various vintages (and just ordered one of the new Pi 4 models). It's my go-to platform for prototyping, especially for ARM-based systems. I keep one on my LAN just to regression and unit test software that I otherwise developed on an Intel platform. I've also used Pis in devices that are more-or-less permanently deployed, like an NTP server that uses a GPS-disciplined chip-scale cesium atomic clock as its oscillator, and a home-built WWVB clock. I'm currently using three Pis in a Differential GNSS system I'm prototyping.
