ESP32-C3 Adblock

The ESP32-C3 Adblock project is an open-source initiative that leverages the compact and efficient ESP32-C3 microcontroller to create a hardware-based network ad blocker. By acting as a DNS-based filter, the device intercepts requests to known advertising and tracking domains, preventing them from loading on devices connected to the local network. This project provides a low-cost, energy-efficient alternative to traditional software-based ad-blocking solutions like Pi-hole. The repository includes the necessary firmware and configuration instructions to set up the ESP32-C3 as a DNS sinkhole, offering users enhanced privacy and a cleaner browsing experience. Designed for hobbyists and privacy-conscious users, the project highlights the versatility of the ESP32-C3 platform in edge computing and network security applications. The source code and documentation are available on GitHub, allowing for community contributions and further customization of the filtering lists.
