Both screens work very well and the package is exceptional value for money. Arrived on time and well packaged
Took me awhile to get them working. A few tips which may help?
Download and use the MCUFRIEND libraries. MCUFRIEND_kbv-2.9.9-Release
2.8" screen (blue PCB) : Identifier and driver 0x6809. Touch screen pins XP=7,XM=A1,YP=A2,YM=6
My calibration int TS_LEFT=932,TS_RT=164,TS_TOP=156,TS_BOT=922
2.4" screen (red PCB): Identifier 0x0000. You need to force the identifier/ID to be 0x9341
On mine the text came out mirrored. Need to edit the MCUFRIEND_kbv.cpp file
Find case 0x9341 (line2570 for me). In line 2571 add INVERT_GS. See line below
lcd_capable = AUTO_READINC | MIPI_DCS_REV1 | MV_AXIS | INVERT_GS | READ_24BITS;
Save the modified cpp file
Use PORTRAIT_REV to get correct screen orientation (printed icons at the bottom)
My Colours were in RGB (565) format and need changing to BGR e.g BLUE changes from 001F to F100. (5 most sig bits need to be least sig and visa versa. Middle 6 bits are OK). There may be a better way of doing this ?
Touch screen pins XP=6,XM=A2,YP=A1,YM=7
My touch screen calibration: TS_LEFT=934,TS_RT=178,TS_TOP=212,TS_BOT=941;
The touch screen mapping will probably need changing to get the correct directions of movement. Where required swap x and y and or left and right values.

Q: Using built-in firmware, picture was a mirror image ?

Saltus The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it's 2-Maga camera, you sure can optimize the software to output the maximum size of photos.
