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

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

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.

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.

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

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.

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.
