TL;DR
The V2X2MAP project combines an open-source Android app with the ESP32-C5 development board to monitor live traffic using Vehicle-to-Everything (V2X) signals. The project was initiated by Peter Holzhauser, who adapted the firmware from an existing ESP32-C5 C-ITS receiver board to work with the Waveshare ESP32-C5-WIFI6-KIT. The V2X2MAP app interfaces with the board, allowing users to connect their Android smartphones with USB On-The-Go (OTG) ports and GPS to visualize nearby traffic signals and nodes.
