X-NUCLEO-IHM03A1 timing

08 Jun 2017

Hi everybody, I am using this module. It is really really great, with the supplied libs runs out of the box.

BUT BE AWARE: The used "powerSTEP01" has an internal oszillator, with a a accuracy of +/-5% (external oszillator is optional)! Caused me lots of trouble until I was aware, mine has a difference of 1,5% (and it is not stable/constant!). Too bad, that on the evaluation board no external accurate oszillator is mounted. So when you need exact timing/speed make sure to solder an external oszillator by yourself (not really easy on the board, but possible).
