The 2.8" version has a similar pcb layout to the 2.4" pcb in your photo.
Your photo has no chip in position U1.
It is always wise to post an accurate photo that matches the item on your desk.
Simple enough from an Ebay 2.8" sale.
Buy XPT2046 chips from Ebay. Or ADS7843 or ADS7846 from US / European distributor.
Solder it to the pcb. The notch on the pcb legend shows which way round.
