One giant vote for LSE crystal and caps on the HDR modules. HDR, for me, is the go-to board type, and has been said before, the LSE is finicky enough with the right caps and everything close to the MCU. Getting it to work on a carrier board could be hit-or-miss, and a breadboard might be a non-starter.
So the list now is all we talked about plus a power led we just decided to add.
Stay tuned…
happy to beta test one for you … You’ll get plenty of feedback too .
