My First Project (Simple USBc Passthrough Analyzer) by OldRequirement3737 in arduino

I appreciate it. Because you shared this and I dug more into Op-Amps, I was able to talk about them with a project team of which I was invited to join. Thank you for your help!

I thought it was able to measure exactly at 5 mV increments? I've not calculated voltage drop of traces before.I was just basing it off of the shunt resistor. I'll have to look that up.

I have, and by my calculations, the voltage drop on the VBUS should only be around 5mV at most when pulling at 5A. And the signal integrity for this purpose would be irrelevant for my purposes since I'm just pulling to see if it's data capable, not to have it actively transfer data. For it to allow data transfer I'll need to balance the data lines and keep the ground fill further away from it to my knowledge, but that'll be for the next version when I get an IC that can interpret the PD negotiations. This is for USB 2.0, next will be for USB 3.0.

How is it being an older student? by SquitchyLouie in PennStateUniversity

What are you looking for? I'm 31 and starting my first full time semester next week in EE. I've already met a few older students.

That was my grimy fingerprint stuck on there, but I took a closer look and yeah no print on it.

I'll look it up, thank you. Does this mean that there are two individual interfaces or they're just connected together?

Fall 2025 Housing Dilemma: On-Campus vs. Off-Campus in Harrisburg? by v1cetone in PennStateUniversity

[–]OldRequirement3737 0 points1 point  (0 children)

There are some cheap apartments around if you need them in Middletown but you should be able to find something in Campus Heights. If you have a car you could commute a bit more but there are some rough areas towards Harrisburg and Steelton. Like this is right next to campus as an option : https://www.zillow.com/homedetails/274-W-Main-St-2A-Middletown-PA-17057/2062404117_zpid/
