Install Pixlet

Turns a Guition JC3248W535 board (the ESP32-S3 3.5-inch touch display sold by diymore and others) into a Pixlet, straight from this page. Works in Chrome and Edge on a Mac, Windows or Linux computer.

Card inPut a FAT32 microSD card in the slot. Pixlets are stored on it.

USB inConnect the board to this computer with a data USB cable.

InstallPress the button, pick the board's port in the browser prompt, and wait about a minute. Keep "erase device" ticked the first time.

Replace the port with yours (ls /dev/cu.* on a Mac, Device Manager on Windows). Download the four files from the links the command names; they are the same parts the button writes.
