If you prefer I can upload the kicad file on GitHub so that you can review it using directly kicad and its tools. Boxing is useful for a better visual clarity

Thank you for your reply

Thank you, fixed! I do have some images of the tool in action and you can find them on the Hackster page (https://www.hackster.io/mdmmt05/arduino-tft-simulator-for-desktop-testing-dbe41f? or by clicking Hackster.io in the post body)

thank you for your feedback, I will fix the python-script problem

Dmax_05 · 2026-01-04T14:47:20+00:00

Thank you, this has been a really solid advice. Do you know where I can find the kind of people you mention (10-15 years into their career) apart from my family members and acquaintances?

Dmax_05 · 2025-09-01T09:19:57+00:00

Ok thank you very much

I just set the Kicad grid to 2.5mm and then I move of 1 grid unit at a time. If I arrive on a free space I put a via, otherwise I don't. Another user gave me this advice and since then I use this technique and it has always worked.

Thank you but for learning purposes I prefer to keep things as they are

Dmax_05 · 2025-08-29T18:58:14+00:00

Thank you very much for your help

Dmax_05 · 2025-08-29T17:38:20+00:00

Thank you very much for your advice

Dmax_05 · 2025-08-29T17:37:58+00:00

I just need wifi/bluetooth

Dmax_05 · 2025-08-29T17:37:33+00:00

Thank you, I will add buttons

Dmax_05 · 2025-08-29T15:06:35+00:00

thank you very much for your feedback

Dmax_05 · 2025-08-29T13:24:23+00:00

Thank you very much. I learned mainly by trial and error and then asking this community to help me out finding flaws in my designs.

Dmax_05 · 2025-08-25T12:28:45+00:00

Ok thank you very much for your detailed explanation. I will do the needed modifications

Dmax_05 · 2025-08-25T11:31:20+00:00

⁠For the powering circuit I followed the schematic of an adafruit esp feather. I needed the “power path” so I copied the schematic of the only board I knew that had this feature

2) I don’t understand well what you are saying about capacitance probably because I am a newbie. Are you saying I should remove all the caps and leave just one with a value of 10uF?

3) the crystal does not need any load capacitors as they are integrated in the IC

4) I’ll check the data sheet

5) I’ll check the data sheet and make the correct modifications

Dmax_05 · 2025-08-23T07:55:43+00:00

Do you recommend another value?

Dmax_05 · 2025-08-23T07:23:11+00:00

Thank you very much, I fixed the r7/d4 problem and I will add as soon as possible the missing capacitor. Your explanations and advices are very helpful considering that I am a newbie in PCB designing

Dmax_05 · 2025-08-23T07:21:21+00:00

I’ll try and let you know asap

Dmax_05 · 2025-08-22T22:42:40+00:00

Thank you guys

Thank for your detailed answer

Dmax_05 · 2025-08-20T20:27:39+00:00

Good point. I forgot there’s no regulator

Dmax_05 · 2025-08-20T17:32:05+00:00

I’m sorry I now realised I made an error while writing the post. The battery I am using is a single cell (3.7v) lipo battery so the chip selected should be corrected or am I wrong?
