Aqua Mitra is a smart aquarium companion built using the CrowPanel 2.8-inch ESP32 HMI display and SquareLine Studio. It provides an interactive touch dashboard to monitor and manage aquarium conditions in real time. The system integrates a DS18B20 temperature sensor for continuous tank monitoring, an SG90 servo motor for automated feeding at scheduled intervals, and relay-based control for lighting and air pump operation. By combining sensing, automation, and intuitive UI design, Aqua Mitra simplifies aquarium care while maintaining a stable and healthy aquatic environment through precise embedded control.

A few simple Arduino examples of using this low-cost compact esp32 + tft touch display module.

This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electronics, and all thanks to this universal and practical display module.

The Vision-Guided Sorting Platform is a functional small-scale prototype designed to demonstrate the principles of industrial automation through a "Proof of Concept" (PoC) model. This project integrates embedded graphics, computer vision, and motion control into a synchronized system, using a custom-built structure to prove the efficiency of the control logic. Controlled through a 7-inch CrowPanel HMI, the platform simulates an automated sorting line. The system is programmed to identify and categorize three distinct geometric shapes: Squares, Triangles, and Circles, showcasing how sophisticated software integration can drive mechanical execution even in a rapid-prototyping environment.

Discover the potential of the 2.8” ESP32 Miner Display by Elecrow: a compact development board that integrates a powerful ESP32 microcontroller with a TFT touchscreen, Wi-Fi, and Bluetooth connectivity. In this project we explore its features, hardware architecture, and development possibilities using the Arduino IDE. The tutorial shows how to configure the board, upload example code, and create graphical interfaces, turning this device into a versatile platform for IoT dashboards, smart home control panels, and embedded HMI applications.

Uses the HMI's onboard outputs to display plant growth information. Ideally, more than one node either through other ESP32 chips, but displayed with several options for personalization.

HMI Dashboard for Euro Truck Simulator 2. Powered by an ESP32-S3 running FreeRTOS and LVGL 8.3, we deliver ultra-smooth 60FPS telemetry that outshines standard tablet-based apps. It is a standalone, low-latency, and professional-grade digital cluster that transforms your truck simulation into a premium driving experience.

Easy-to-build VFO (Variable Frequency Oscillator) that features a clear, touch-enabled circular display with retro-style virtual scales.

In this project, we’ll turn the Elecrow 7" ESP32-S3 HMI display into a complete UPI payment interface for a vending-machine-style system. You’ll learn how to design the UI in SquareLine Studio, generate a dynamic UPI QR code based on selected items, and print a payment receipt using a thermal printer — all driven by a single ESP32-S3 board.
