In this project, I built a clean and interactive 12×5 grid system on a 10.1" display using the ESP32-P4 Nano from Waveshare. The system displays up to 60 characters on screen and is controlled wirelessly through a Flutter-based mobile app via Bluetooth Low Energy (BLE).
The UI is powered by LVGL, complete with card-style animation effects and sound feedback to enhance the user experience.
This project demonstrates how capable the ESP32-P4 is, especially when paired with a high-resolution display and optimized graphics. Text input is sent directly from an iPhone/Android app, and characters animate as they fall into place.
This entire project is open source — including both firmware and mobile app code — and available on GitHub.
Tech Stack:
ESP32-P4 (Waveshare Nano)
LVGL 9 for UI and animations
Flutter for mobile app (BLE support)
Power usage:
With the brightness set to 100%, the system consumes about 830 mA at 5V (~4.2W), allowing it to run for ~2.2–2.3 hours on a 3000 mAh power bank.

This is an early demo of my ongoing project to create an offline GPS map viewer using the ESP32. Inspired by a similar Raspberry Pi and E-Paper build, this version aims to load map tiles from an SD card and display the current GPS location—completely without internet. Stay tuned for updates as the project progresses!
