Tiny PCB With Kicad Files #9

Closed florianbrede-ayet closed 11 months ago

florianbrede-ayet commented 11 months ago

Hi, first thanks for the project and your effort, I've finally been able to reduce my "LG Artcool Gallery (Multi)" to bearable fan speeds, which helps a lot. I still have different issues with my MU3R19 setup, because in heating it doesn't modulate correctly. But unfortunately, no error is ever reported, so I have to continue looking for an LGMV dongle.

Anyway, the Artcool Gallery is tight on space and the parts of your PCB are quite hard to source and rather expensive, I designed a tiny pcb with an ESP32 DevKit footprint (around $8 per piece assembled at jlcpcb): image

The files are currently in my fork, but if you're interested I could create a PR: https://github.com/florianbrede-ayet/esphome-lg-controller/tree/main/hardware-tiny

This is really nice.

This was my first PCB so I tried to follow the project I based the hardware on as much as possible to not break something, but it's good to have an alternative design that works. I thought the TI LIN transceiver was the only one that didn't have the timeout feature but you found another one :)

If you could do a PR for the hardware-tiny directory, that'd work. I could also link to your fork in the README file - let me know which option you prefer.

I never expected this project to get this much attention :) I'm now thinking about rewriting the software a little to make it easier to send/receive other message types.

Ohhhhh wow this is awesome i wish i had seen this before i placed the order with pcbway. I also have some Artcool Gallery so this will help me. I think they soldered some parts incorrectly but i am waiting on verification otherwise if they did i will kindly ask them to change them for this layout.

@florianbrede-ayet did you want to create a pull request for this? I think this could help a lot of people.

florianbrede-ayet commented 11 months ago

@JanM321 just did, it got lost with my fork reset.

@mshrem hard to tell from the photo if diodes are reversed, but the capacitors are non-polar I guess? Anyway, I'm not sure if the larger footprint would fit inside the Artcool Gallery, that's why I designed the small PCB: image

Thanks! I merged the PR and added a comment to the README about this.
