INTEGRATION OF A STANDARDIZED BOULDERING BOARD INTO AN ARCHITECTURE FOR SIMULTANEOUS TRAINING MANAGEMENT

In this study we have developed a low-cost, open-source architecture based on ESP32 LED matrix controller managing a 198-hold, 18×11 bouldering board with a RESTful web application that unifies member management, attendance tracking, and training session control under a single interface accessible to multiple users simultaneously. The system was deployed and validated at a small indoor climbing facility over a two-month period. Results indicate that the integrated architecture reduces front-desk administrative time, improves training efficiency and increases the usage of the training board.
