Futbol's Tech Upgrade: The New Substitution Board Revolutionizing Liga MX

**Futbol's New Tech: A Closer Look at the Substitution Board** Mexican soccer fans witnessed a new technological innovation during a recent Liga MX match: a digital substitution board. This innovative device, explained in a recent TUDN video, streamlines the substitution process and is a significant improvement over older models. The video features an interview with Daniel López Zúñiga, one of the engineers who designed the board. "It lights up from the left side," Zúñiga explains, demonstrating how to input player numbers. "With these buttons, we select the number. For example, here we're putting in 33." He then shows the other side, using a green button to indicate a player entering the game. The board also features a memory function, allowing for up to five substitutions to be stored. The board's lightweight design (3.7 kilos) and long-lasting battery (nine games) are key advantages. The video also notes that each team has two boards as backup in case of failure. This new substitution board represents a significant advancement in soccer technology, improving efficiency and providing a clearer display for players and fans alike. The sleek design and user-friendly interface are already making a difference on the field.
