Ultrasonic Anemometer

cheers! that clears up a lot :slight_smile:

I am making a pcb design for both the analog and digital boards... so if i am done i will share with you.
from first check i can just hook in the ultramp in top left of analog, however it currently is 8v and ultra-amp is 5v

i assume H9 and H10 on analog are testpins too?

one thing i was wondering, you have a lot of gnd's to seperate holes, i could just lead them to 1 ground plane right, since you seem to lead them to actual pinouts

thanks a lot for the help
