This is a specially designed 2.8" touchscreen expansion and interface board for the Raspberry Pi Compute Module 4.
The main display board offers a compact 2.8" display with 480x640 resolution and 5-point capacitive touch combined with toughened glass. Your CM4 (sold separately) clicks into the display board and breaks out various connectivity options including a MicroSD slot, USB 2.0 port, camera connector, GPIO expansion header, USB-C power/programming port (4A recommended!) and micro-HDMI port. You will also find a status indicator LED and boot switch for your convenience.
The additional interface expander board (included) connects to the main display board via the GPIO expansion header and offers three additional USB 2.0 ports, a Gigabit Ethernet port, M.2 slot for comms modules/storage and an M.2 status LED!
Usage and setup guidance can be found via the Waveshare Wiki.
