1 month ago Would be very interested to see some of these numbers if anyone could run tests, particularly curious how power draw compares to the standard Pi 4 as the CM4 datasheet says it uses slightly less.

1 month ago @aspencuozzo - Ha! I completely forgot I haven't filled in all the details here. Will do so today.
