Added new board sunton_esp32_2432S024C

[oschettler]

Dear circuitpython team,

I have added a new board. This board is a Sunton ESP32_2432S024C. I have no affiliation with this vendor, but am a user of the board.

The board is one of the Cheap Yellow Display ("CYD") variety. It has a 320x240 pixel screen (ILI9341) with capacitive touch (CST820), an SD card slot, an RGB LED, and a light sensor.

There is some documentation on the board and some working configurations as well:

• Dokumentation (as ZIP), linked from the Aliexpress site above
• a library for Micropython. The source coude in cydc.py contains a list of all the pins.
• a board definition for platformio. This is part of a project to provide board descriptions for all the (yellow) Sunton boards.

Hi - there are multiple similar Sunton boards. There is

• https://circuitpython.org/board/sunton_esp32_2432S032C/ -- 320x240, 3.2", uses an ST7789
• https://circuitpython.org/board/sunton_esp32_2432S028/ - 320x240, 2.8", uses an ILI9341

Is this board pretty much the same as the second one, except for the display screen size?

Hi, yes, the boards are indeed quite similar. So much so that I started with the board files from sunton_esp32_2432S028 (both use an ILI9341) and took the touch configuration from sunton_esp32_2432S032C (that one uses a CST816, the sunton_esp32_2432S024C uses a similar CST820).

This looks good. I looked at the other boards, as you mentioned. It seems a bit crazy that the boards all use different combinations of display controllers and touch controllers, but they may use the parts that they can get.

One Q re pre-commit version.

Thanks! Could you also submit a PR to https://github.com/adafruit/circuitpython-org to describe the board? Guide here: https://learn.adafruit.com/how-to-add-a-new-board-to-the-circuitpython-org-website

The earlier draft PR has a few pin/feature differences that could be differences in unique builds of the devices. The draft also makes more of the touch interface visible through board attributes.
