Hello everyone,
I'm a senior mechanical engineering student working on a project where I need to emulate the signals generate from the PCB below which are sent to a more complicated PCB, but the silkscreen print on the PCB was for some other design that it was originally used for. Anyway, I've attached pictures of the components that I need to identify - the ones covered in the red goo. I'm sure this is something common, but my best guess would have to be some sort of capacitor.
Thanks for the (potential) help!
Ethan
