Anyone know where there is a scanned or web version of
the SMC HDC9224
data sheet and pinout?
Try a search on
http://www.freetradezone.com
for something containing hdc9224 and you'll
find the datasheet (four times). The App Notes
both look useful too.
Note - freetradezone is about to stop being free,
so don't hang about!
