Trastikata, can you please add sources of the LCD modules you used in this website?

Hello SeanG_65,

did you mean purchasing sources like Aliexpress or some code sources?

You can use any module with the same graphic driver (chip), just the pin-out might be different but this is something particular to specific project design. That's why I described the pin functionality for the different types.

Here some Aliexpress:

Parallel port:
ILI9486 With Touch - search phrase "TFT 3.5 480x320 ILI9486 With Touch 34P"
https://www.aliexpress.com/item/1005007461863045.html    - select from the types "ILI9486 With Touch" 34P

ST7796 WithTouch 34P - from the same link as above but different driver.

SPI port:
ST7789V With Touch - search phrase "TFT 240x320 2.8 SPI TFT Touch"
https://www.aliexpress.com/item/1005004557916570.html  - select "ST7789V With Touch"

ILI9341 - from the same link as above but select different driver.

P.s. If it is a code sources that you need, can you specify because I am not sure what would you mean.

Hey Trastikata - is there any availability of that development board shown on the hardware page? One of those together with a couple of screen choices would be really useful!

Hi Trastikata

can I find schematics on picgraphic.com?

Kind regards Sommi

Hello Peter Truman, I got 5 bare PCB's from JLCPCB, and I have 3 PCB's left. I don't need the boards and I can provide the MCUs (I have few tens of them) and connectors but you'd need to populate the boards with passives 0805 sizes and solder by yourself everything.

As John said the schematic is there, and there's nothing critical in terms of values on this design and all passives are pull-ups and filter caps.

Maybe only the crystal capacitors can't vary that much from 12 to 18 pf, all the rest can differ as much as an order of magnitude ... whether the pull-up is 10k or 1k or the protection resistors are 10 or 100 ohms or the filtering caps are 47uf,22uf or 10uf or 1uf doesn't matter really.

Thanks Trastikata, that's EXACTLY what I needed.
