USB-C Power Meter Enclosure Design!
So awesome that onshape is free! Printing overnight on my Bambu, lets see how it turns out...

@ArrowAir_ Thanks!!

Layout Complete! Yusss! 🪇

Got this 4 layer board to be smol as 33.5x25mm (in comparison to the display which is 21.5x16.64).

Next up: bringup and enclosure design...

[jun @Sweetrollls]

@ArrowAir_ Wow this is awesome

[jun @Sweetrollls]

Heres it plugged into my mini hotplate:
The plate draws about 20V, where it linearly draws power until it plateaus at about 42W (2.1A). You can also see the graph drop immediately to around 0.1W when the plate turns off. Fun stuff!

USB-C Power Meter (status: complete!) 🎉

This fun little side project!
Features: curr./volt./pwr readout screen, pwr/curr. vs time graph, and an easter egg…

Here it is reading the power/current draw when charging my phone.

Quick lil side project time...

A friend had one of those USB-C power meter devices lying around and wanted to make one of my own rather than buying one OTS!

Features:
INA238 Power Monitor + STM32G030 + SSD1315 Display
(0.3V-48V, 5A)

Schematic ready to go, layout next 👀

[jun @Sweetrollls]

@willreil Oh that would be cool...
Im gonna have a repo to all the firmware, pcb design files and onshape design so you can reference. Ill link it on the final post for the project!

[jun @Sweetrollls]

@willreil Says you man! Im constantly inspired by your work! Im flattered thanks :)

[jun @Sweetrollls]

@IDV_FPV Thanks! Took some reprinting to get it right, but works!

[jun @Sweetrollls]

@IDV_FPV @HQ_NextPCB So excited to see them working!

@GavinHuang6666 I designed this, its a small side project im doing while im currently studying electrical engineering

yay display works; got a little spaceship game going to test the buttons and a page to show INA readings

[jun @Sweetrollls]

the startup beep is an I2C bus scan (long beeps indicate devices found), funny way to debug I2C peripheral connections lol
