#153577 - Ferrite beads trick! Responding to: ???'s previous message |
I added ferrite beads to all wires comming in and out of the box on the inner side of the connectors and as expected I got more stable reading without averaging. I can't wait to see what happenes when I surround my boards with Faraday cage connected to analog gnd and do averaging of 16 samples!
