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.

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.

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.

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.

CrowCaddie transforms the Elecrow CrowPanel 7.0" ESP32-S3 HMI into an autonomous, commercial-grade golf cart terminal combining a visual caddie HUD, long-range fleet telemetry, and an active safety governor. Operating on an offline-first architecture, CrowCaddie renders high-resolution 800×480 hole maps and live satellite yardages to the pin at 60 FPS using LVGL. When carts approach restricted turf (greens, bunkers, hazard zones), high-speed point-in-polygon algorithms trigger an onboard relay spliced into the cart's forward microswitch—safely cutting forward acceleration while leaving reverse open so golfers can back away. For fleet tracking, carts broadcast compact 20-byte telemetry over 915MHz LoRa to a silent clubhouse gateway kilometers away. At night, carts wake on barn WiFi to pull delta updates—downloading course blueprints, 280×150 sponsor banners, and calibration offsets in under 2 seconds.

In this video, I demonstrate the simplest way to build an advanced, keyless security device using the CrowPanel 1.28-inch-HMI ESP32 Rotary Display. This module is a game-changer for DIY electronics because it integrates a touch screen, a physical button, and a rotary encoder into one sleek unit.

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.
