PDF specification sheet for the PG320240LRF-CNN-H-33 graphic display module. The trailing 33 may indicate a 3.3 V logic version, but treat that as unconfirmed until you read the electrical table. The 320240 figure points to a 320 x 240 dot panel. Inside you would normally find pinout, absolute maximum ratings, interface timing, backlight data and a dimensioned drawing. Match every letter of the suffix to the label on the module, as variants differ in supply voltage, backlight and temperature range.
