fully functional VA for home assistant

We continue with the ESP32 2.8 inch display development board from Elecrow.

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.

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.

This module from Elecrow has endless possibilities for making DIY projects in a relatively simple way, without need for soldering or other hardware work.

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.

How to make 5-day precipitation forecast device with probability percentages and Current weather conditions (temp/humidity/pressure)

A polished and modern HMI design for an aquarium controller, built with LVGL and SquareLine Vision. Focused on clean layouts, smooth animations, and intuitive rotary control to create a UI that stands out.

This project successfully merges the nostalgic charm of a vintage tube radio with the power of modern internet streaming using the Crowpanel 7-inch Pi Terminal.

Build a wireless, portable smart-home control tablet

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

This project combines the modern capabilities of the CrowPanel ESP32 Display module with a true retro radio, focusing on the manual, drawn-scale station selection.
