E-PAPER IOT SWITCH / ESP32 APPLICATION
E-Paper IoT Switch
Personal project - Iot switch with esp32c5 and 3.7" epaper display
About this project
About this project
A KiCad design for an IoT switch with a 3.7-inch 240x416 black-and-white e-paper panel and an ESP32-C5 module, with every part ordered from AliExpress and the boards soldered by hand. The write-up is a design log: a power budget and block diagram first, a schematic drawn from datasheet reference circuits, a PCB shaped around the enclosure, and a BOM kept in the spreadsheets folder. There is no finished firmware. What exists is work on a driver layer that would let the GDEY037T03 panel talk to the Adafruit GFX library, shown by a single screen test, so the software is a starting point rather than a working switch.
