I’m deep diving into ultra-low power / BLE (Bluetooth Low Energy) domain to future support some efforts requiring motor remote control.
As such, I decided a good practical use case would be developing a BLE-controlled smart-watch.
Since this here forum is not the right place to do that, I moved my development to:
If anyone is interested in the progress, I post my work there, and hopefully if successful, I’ll make it available to you later.
Hopefully you could later use this effort to support your development of remote stand-alone motor control.
Updating the progress with something that could potentially be used as a SimpleFOC MCU, you can see the full progress up the original post.
The tiniest nRF52 break-out development board and the tiniest board I’ve ever created.
External DC/DC converter inductance.
External TCXO 5ppm accuracy (about 2 minutes/year deviation).
80 micron traces.
BGA MCU (the one JLC dropped and they had to re-fab my PCB…)
The real question, will it work? Stay tuned!
wow! how much extra do you pay for that?
$200 for 2 including shipping. I believe it’s about $50 extra. They also failed to manufacture on the first try, so we went for round 2, lol.
Small update, moved to hackaday.io
