How to Build an Arduino FTP Server: UNO/Mega, Ethernet & SD (SimpleFTPServer v3.x)

Managing files on an SD card connected to an Arduino often means physically removing the card, plugging it into a computer, and copying files back and forth. This process can be tedious, especially for projects mounted in enclosures or hard-to-reach places. But what if you could manage those files remotely, over your local network, just like you would with a web server? That’s exactly what the SimpleFTPServer library enables.

ESP32-2432S032 (3.2″ Sunton “Cheap Yellow Display v2”): pinout, datasheet, schema and specs

Sunton’s ESP32-2432S032 is the 3.2-inch successor to the original 2.8″ Cheap Yellow Display (CYD).
It keeps the same ESP32-WROOM-32 MCU and “all-on-one” concept, LCD, touch panel, micro-SD, speaker amp, RGB LED and light sensor already wired, while adding an on-board Li-ion charger/boost (IP5306) so the board can run from a single-cell battery as well as 5 V USB.
