This project transforms an ESP32 microcontroller into a portable computing device that fits in a pocket. By combining the ESP32's wireless capabilities, processing power, and a compact display, builders create a minimal yet functional computer for running simple applications, accessing the internet, and experimenting with embedded systems.
The guide provides a complete parts list, wiring diagram, and step-by-step assembly instructions for connecting the display, input controls, and power management to the ESP32. Included firmware examples demonstrate how to build a basic operating system interface, handle user input, and manage the device's limited resources for practical everyday use.
