This article announces the Private AI Agent Platform

Announcing esp-hal 1.0, the first Rust SDK for embedded devices.

Learn how to set up the ESP32 Arduino Core development environment, including Arduino IDE installation and ESP32 board package setup using both the Board Manager and manual Git installation methods.

This guide explores how to utilize flash memory for persistent data storage in NuttX-based embedded systems, covering SPI Flash fundamentals, file system options (SmartFS, SPIFFS, LittleFS), and practical implementation of a boot time logging application with Wi-Fi and NTP synchronization.

This blog post introduces the esp-wifi-remote component, which extends Wi-Fi functionality to ESP32 chips that lack native Wi-Fi support. We will explore the esp-wifi-remote ecosystem, its components, architecture, and integration with esp-hosted.

Fast and secure device restoration during boot-up is critical for real-time IoT applications like smart lighting. In this article, we explore how to reduce boot-up delays by restoring device state early, directly from the ESP-IDF bootloader.

Espressif is streamlining RED Delegated Act (RED-DA) compliance by providing pre-certified firmware platforms, documentation templates, and partner support to help developers meet the upcoming EN 18031 standard. With flexible pathways including self-declaration and third-party assessments, developers can accelerate EU market readiness for Aug 2025 and beyond.

This article extends the NuttX motor control system with inertial measurement unit (IMU) sensor integration for vibration measurement and wireless data streaming capabilities using the ESP32-C6 Wi-Fi connectivity.

In this article, we explore a simplified ESP32 boot process using single-image binaries to speed up build and flash times — ideal for development workflows. This approach sacrifices features like OTA updates but enables faster iteration.

Mosquitto – the industry-standard MQTT broker – has been ported to ESP-IDF. Its lightweight version retains Mosquitto’s core functionality and security features to run on resource-constrained IoT devices. This MQTT broker is ideal for edge computing, testing, and standalone IoT deployments. In this article, we will do an overview and show you how to get started.

This article demonstrates how to implement motor control and speed sensing on an ESP32-C6 using NuttX RTOS. It covers setting up MCPWM for motor control, ADC for potentiometer reading, and quadrature encoder for speed measurement. The implementation showcases NuttX’s real-time capabilities through a practical example using common peripherals and sensors.

Discover the ESP32-P4 EYE DevKit — a compact, camera-focused development board designed for real-time image processing and edge computing. Learn how this powerful, low-cost solution can accelerate your next smart camera or IoT project.

This guide helps manufacturers of wireless-enabled products based on Espressif modules understand the RED DA (EN 18031) cybersecurity requirements, identify their product’s category, and determine the right path to certification before launching in the EU market.

This article provides a high level overview of the security architecture of the ESP RainMaker IoT platform, covering all aspects like device hardware and network security, client network security, authentication and access control, user-device mapping, cloud data security and certifications.

This is an introduction to the critical embedded system debugging techniques of tracing and profiling within the Zephyr RTOS. After reading this article, you can use Zephyr’s native tracing tools to gain a visual, in-depth understanding of system dynamics, helping to evaluate performance, spot timing issues, and diagnose complex problems like memory leaks or thread interaction glitches.

This article explains the booting process of Espressif devices up to ESP32-C6 (and probably newer devices).

How Pytest is used for testing the NuttX RTOS on Espressif devices.
