Review of the Waveshare ESP32-P4-Module-DEV-KIT-C featuring a large 10.1" display in a compact Raspberry Pi form factor. Includes a detailed step-by-step guide for LVGL GUI development using ESP-IDF and pure Espressif components: from MIPI-DSI initialization and touch integration to the final application.

A compact slave clock controller with ESP32-C3 and DRV8871 H-bridge. The circuit synchronizes automatically via Wi-Fi and NTP, has a battery backup for power failures, and costs only a few euros to manufacture. Complete instructions with circuit diagram, components, and finished code.

The new CrowPanel Advance 7" uses the ESP32-P4 for native MIPI-DSI interfaces. However, the test reveals not only high computing power but also a design problem with the co-processor: Why the hardware architecture of the ESP32-C6 becomes a dead end for ESP-NOW and for whom the board is still worthwhile.

A small Geiger counter, an ESP32, and a custom driver – that’s all you need to detect radioactive radiation. In this article, I show how to connect the RadiationD-v1.1 board, count pulses, calculate CPM and µSv/h, and easily integrate the sensor into your own projects.

Following the theoretical foundations of LoRa radio technology, this article presents its practical implementation. After an overview of the most important LoRa chips from Semtech, I introduce a driver for the SX1262 and a practical tool for conducting initial LoRa experiments.

A lightweight library for the ESP32 for dynamic configuration of Wi-Fi access data. Implements a web server & captive portal for user-friendly provisioning. This allows the SSID, password and time zone to be transferred to the ESP32 without a special app.

This guide will show you how to install the Lyrion Music Server (formerly Logitech Media Server) on a Raspberry Pi 5. This version of the server uses an NVMe SSD instead of the standard SD card, making it extremely powerful. I have also housed it in a retro-style case.

The ESP32 weather station is now over a year old. So it's high time for an update. I have therefore spent the last few weeks developing a completely improved version of the weather station. I would like to present the changes to you in this article.

How can you control higher loads such as LED strips with the ESP32 when a single GPIO pin can only deliver a few milliamps at 3.3 V? In this article, I take a practical look at different transistor solutions for switching higher currents with the ESP32. I compare a Darlington transistor with three MOSFETs and show, which types are suitable for logic-level control.

The ESP32-S3 7 inch display from Sunton is one of the few boards that combines a modern microcontroller with a comparatively large display. I will show you how to get it up and running with just a few steps.
