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

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...

gm. every layer of our multipurpose drone Quiver, out in the open. just how we like it.

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. Full project repo: github.com/JunKimmmy/USBP…

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 👀

@Sweetrollls :)
I'm looking to add sideways buttons like you have, I would love to hear more about the design and the print you made for it so I can do something similar on this keychain pcb

CO2 puck boards have arrived from @HQ_NextPCB!
They sponsored the project and I'm genuinely impressed with the speed. From uploading the files to delivery in Belgium took only 16 days, even with some niche sensors they had to source.
Looking forward to test them when Im back🤞

CO2 puck has been assembled! @HQ_NextPCB sent some preview images for inspection. Looking good 🤞 That lux sensor looks incredible, can't wait to stick it under a microscope.

@GavinHuang6666 I designed this, its a small side project im doing while im currently studying electrical engineering
English
@Sweetrollls Is it a project designed by your school or your own hobby?🧐

@shantanugoel Its an ALIENTEK DP100, very smol and portable

@akohlsmith @willreil Yeah there’s definitely different types, with different pitch sizes.
These two have the same internal controller type (SSD1315) just different pad sizes:

^one i used to work with the fpc connector

@Sweetrollls @willreil Interesting; the ones I used were meant to be hot barred, no connector. Maybe this is a different variant, or maybe someone did make a connector for them.

How hard is it to assemble a screen like this on to a PCB? Would I be better off with the modules or is this the way to go?

LCSC packaging 🔛🔝

@willreil FPC connector (FPC-05FB-30PH20) is on the board itself, so assembly is just clipping in the cable. Went this route over modules to save space and remove any mechanical constraints (no standoffs, no added height) but it requires some driving circuitry on the board
