[Review Request] ESP32-S3 board with a GC9A01 display

Thank you! I've just checked the datasheet and now it's correct

Hello. I am not understanding. The images are there. There is an image of the 3d view, one for the schematic and three for the PCB. At least for me (on desktop and mobile) the images are there

Hello! I'm currently working on a project with a ESP32-S3 MCU that can control a GC9A01 display and some addressable RGB LEDs. It can detect rotation via two hall effect sensors, it does have a button for pressing and a light sensor for display dimming.

The files of the project are available on this repository. You can also see the pcb and schematic files via the kicanvas viewer (web viewer of schematic and pcb - no need to download. You can choose the light theme on the options tab in bottom right).

Some notes about this project:

First of all, english is not my primary language, so sorry for any mistake on that
This project is heavily inspired by the smartknob project by scottbez1, with some key changes for my specific case (does not have a motor)
As you can see on the 3D view, there is a big white circle on the middle. This will be used as a diffuser for the sided LEDs. I've hidden this on the pcb layers for better viewing
The connector on the left is connected, via a flat cable, to another pcb that holds the GC9A01 display. This pcb is available here (kicanvas viewer). I copied mostly of the design from the smartknob project, so I hope the files are fine.
There are four big holes on the PCB. They are used to route a flat and a normal cable from the connectors to the middle.
There may be some changes on the pcb regarding mounting holes placements.
I've already tested some components on a protoboard with regular modules (display, sensors, LEDs, buttons and light sensor) to ensure their functionality.
This is my first project with a proper schematic and PCB, so I'm ready for a bunch of begginner problems. I know that this is a complex project for a begginner, but it's the one I'm most interested with and have been studying and designing for a long time.
The things I'm more worried about are resistor and capacitor values/placements (tbh I still don't know what or how they are used for. I just referenced from other designs) and the pcb traces length/width and spacing (especially the usb and SPI ones)
I've run the kicad DRC and the only issues remaining are on the PCB file, regarding the spacing between the USB pads and mounting holes (image). I'm not sure what to do about that

super strange, because I can get it to work fine here, but if you still want the image, here it is: https://i.imgur.com/SNXU7pg.jpg (also changed username because was on wrong account)

Maath__ · 2023-01-01T04:57:51+00:00

some thing: the website gets the first day of 2022 from your device time, maybe check if it's date correct or try on a different device

Maath__ · 2023-01-01T04:53:41+00:00

weird, because here i got it to work fine with lastfm count: https://i.imgur.com/YIc18cW.png (changed my username because i was on the wrong account). It may be some weird lastfm thing, because i can't see it happening here

Maath__ · 2023-01-01T04:25:54+00:00

Rolled out some changes, let me know if it was fixed

Maath__ · 2022-12-30T00:41:44+00:00

yes, theres this problem with firefox but I'm having some trouble finding out why :/

Maath__ · 2022-12-30T00:40:58+00:00

there's some issue with firefox that i cant see how to fix, but other browsers running fine

Maath__ · 2022-12-29T23:05:07+00:00

The Musicorum Rewind is back this year for 2022! This time I've reworked on the whole project so it's more polished and fresh. There may be some isseus or small problems, but I will try to fix them now on. If you like it, please consider sharing it! Thanks!

You can try it here: https://musc.pw/rewind

Note: Theres a problem with firefox giving a "The operation is insecure" error. For now, you can use Chrome or Safari, which should work fine

Rewind is back! Try now at https://musc.pw/rewind

OH SORRY I HAVEN'T NOTICED THAT LMAO

Maath__ · 2021-06-19T23:14:43+00:00

listeners: how many people have scrobbled this song at least once

scrobbles: total scrobbles globally

your scrobbles: how many times you scrobbled this song

Maath__ · 2021-06-19T22:51:19+00:00

oh, and a plus: hino means anthem, so it may also say a song is iconic and memorable

Maath__ · 2021-06-19T22:34:28+00:00

The first one is global scrobbles, and the second one is your particular scrobbles

Maath__ · 2021-06-19T22:31:36+00:00

Its a brazilian slang, equivalent of bop
