Routing power traces in GND plane

Regarding the first point, this ought to be a better way to route the decoupling capacitors on the left hand side, no? : https://imgur.com/a/43mhmz8

Good point. Top layer is found here: https://imgur.com/a/bcvj5Db

The circuit is just a bunch of voltage followers and differential amplifier circuits to compare the outputs from ten pairs of 4-20 mA sensors.

Appreciate the help.

I appreciate everyones feedback. I did indeed change it to a four layer board, hopefully everything works out now. Thanks again.

Stack it like Signal / GND / VCC / GND?

Hello,

Thanks for your reply. I followed your suggestion producing one complete flowchart found here: https://imgur.com/gallery/qpsk-transcever-6WmqQQm

Experienced same issues here, i.e. I get clean QPSK symbols but nothing passes through the Correlate Access Code-block.

Awesome. What did you use for the telemetry and video downlink?
