Resistive?! Yep - you don't see many resistive touch displays for the Raspberry Pi these days, however they have a place in certain projects/scenarios, and they cost less than their more-common capacitive counterparts - so this might be ideal for your project!
It's a 3.5" IPS panel with a 320x480 resolution offering 262K colours, 170° viewing angles and 60Hz refresh rate - all controlled via SPI. It features resistive single-point touch and mounts to the rear of your Raspberry Pi using pogo pins, which keeps your GPIO header and top of the board completely free for HATs and coolers.
A connector on the rear of the display can be used with the included GH1.25 11-pin cable to use this display with other development boards, with ESP32-S3 examples provided in the product wiki.
It's an interesting combo of OG resistive touch technology combined with a modern 60Hz IPS panel, SPI communication and pogo in mounting.
Note: The display orientation is portrait by default, 320x480 resolution (H×V). Change the software config for landscape display.
Raspberry Pi not included.
