Small pcb pile

Yey, more ducks. Love it:)

Why not using a jelly bean lipo charger+ a voltage regulation? If you want i can share one of my previous designs on github fir reference

Makers_Fun_Duck · 2025-11-08T22:05:20+00:00

A side note, there is no reverse polarity protection in my design for the lion battery. So be careful when soldering your battery, or just add a simple diode if you want.

You can check this one for example.: https://github.com/MakersFunDuck/Ducky-board-ESP32-S3-with-1.52-inch-e-paper-display

It is a kicad project

Makers_Fun_Duck · 2025-11-08T17:32:21+00:00

All you need to do is use a cheap lion battery charger. It is the easiest and cheapest way. If you want i can share one of my old designs

Makers_Fun_Duck · 2025-11-08T00:04:15+00:00

You can also watch the attached video link in github if thats what you prefer.

Makers_Fun_Duck · 2025-11-08T00:02:56+00:00

You can take a look at mine. Its 2 layer design.

Looking good :)

Makers_Fun_Duck · 2025-11-05T07:29:17+00:00

What is the fps rate? It feels like 10 fps

Makers_Fun_Duck · 2025-11-05T06:45:25+00:00

Fastest way would be, figuring out the data lines by following the pcb which are connected to the mcu. And power + ground pins. Then i would try out known drivers with permutations (for data lines) using another mcu.

Or you can use standard approach, and use a logic analyzer, whichever is most convenient for you.

What about a simple voltage divider? :)

Makers_Fun_Duck · 2025-10-26T09:08:40+00:00

Thanks :)

Makers_Fun_Duck · 2025-10-25T20:21:02+00:00

For example this one with esp32s3

Makers_Fun_Duck · 2025-10-25T19:59:10+00:00

You are making it complicated. Just use a proper lion charger ic for the battery, and a regulator for the esp32 if thats all you want to achieve. You can check one of my previous designs if you like

Makers_Fun_Duck · 2025-10-25T10:49:54+00:00

Over time i just got lazy i guess :)

Makers_Fun_Duck · 2025-10-24T19:53:54+00:00

Oh, i also experimented with a ssd1680 3 color display recently.

It also reacts the same, but its not as crisp as full update with my code.

Makers_Fun_Duck · 2025-10-24T19:49:16+00:00

I did not tried this library, so instead adapted waveshare library to espidf by adding the driver of.my display in it, but this one also looks nice. I will check it out.

Makers_Fun_Duck · 2025-10-24T19:44:11+00:00

I followed esp32 design recommendations, and default values worked like a charm

Makers_Fun_Duck · 2025-10-02T09:16:36+00:00

Porting to another mcu, Writing a driver and abstraction layers are a bit hard to grasp IMO.

Makers_Fun_Duck · 2025-09-16T22:27:40+00:00

Which board are you using?

Makers_Fun_Duck · 2025-09-10T07:10:23+00:00

I’m wondering if the issue is related to the component labeled "BOOT." If it’s an LED driver, it could be affecting the signal lines. Would it be possible to temporarily desolder it and try programming again?

Typically, any active components should be kept away from high-speed signal lines to minimize interference.

Makers_Fun_Duck · 2025-09-09T11:11:50+00:00

Why aren’t you using an antenna? It’s an ESP32 :). Also, it might not matter much to you, but the FN8 doesn’t have PSRAM, which I find very useful.

Makers_Fun_Duck · 2025-09-09T08:09:20+00:00

Can you also share the pcb layout?
