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.

Introduction of the 5″ CrowPanel ESP32 Display, featuring a capacitive touchscreen and a resolution of 800×480. As its main control processor, it uses the ESP32-S3-WROOM-1-N4R8 module. This is a dual-core 32-bit LX6 microprocessor with integrated wireless capabilities, supporting both Wi-Fi and Bluetooth. It runs at a main frequency of up to 240 MHz, delivering powerful performance suitable for IoT applications.

This guide describes how to build the XIAO METER demo board, designed to easily test a wide range of sensors using the XIAO SAMD21 by Seeed Studio, the smallest member of the Seeeduino family. The module measures only 20×17.5×3.5mm, and features a Cortex-M0 microcontroller, 11 I/O pins, and supports UART, I2C, and SPI communication. It is fully compatible with the Arduino IDE.

Let's see how to install the MicroPython programming language and the Thonny development environment on the Raspberry Pi Pico.

Let’s take a look at this interesting All-in-one Starter Kit for Pico 2—a kit designed for learning electronics and programming, ideal for beginners and beyond. It allows users to begin their journey with the Pico 2 RP2350 processor in a simple and fun way. The kit comes in a small suitcase measuring 195 × 170 × 46 mm. Inside, there’s a single board equipped with as many as 17 sensors or modules serving various functions. It also features a 2.4″ full-color TFT touchscreen.

Hello everyone, makers and robotics enthusiasts! Today I want to talk to you about a component that is capturing my attention and that could revolutionize your next HMI (Human-Machine Interface) projects: it is the CrowPanel ESP32 4.2” E-paper HMI Display produced by Elecrow
