In this tutorial, I show you how to build a tiny panel that displays YouTube views and subscriber counts using a 2.9" e-paper display module from WE-ACT ($8 on AliExpress). This low-power project runs on a small LiPo battery for 60+ days without charging!
What You'll Learn:
-Setting up a 3-color e-paper display with ESP32
-Connecting components (ESP32, display, battery, charging module)
-Programming the display using GxEPD2 library
-Retrieving YouTube statistics with YouTube Data API
Components:
- ESP32 Wroom (without devboard)
- 2.9" e-paper display (296px wide)
- 200mAh LiPo battery
- Type-C charging module
- 3.3V converter
