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.

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.

A Nextion-like HMI, but without the pain. This ESP32 firmware uses plain JSON over UART to create and control the UI dynamically. No editor, no compiling screens — just send commands and get events back. Simple, transparent, and made for real embedded projects.

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

How modern electronics can completely replace and improve the classic mechanical instrument, offering digital precision in a beautiful retro package.

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.
