The rapid development of microcontroller technology has driven innovation in digital-based public information systems. This study aims to design and implement a digital information display module based on the Internet of Things (IoT) using ESP32S and LED P10 as media for information dissemination at the Department of Communication and Informatics (Kominfo) of Tanjungbalai City. This innovation was developed to overcome the limitations of manual systems that cannot update information in real time and lack internet integration. The system consists of an LED board measuring 2 meters × 62 cm, composed of 12 LED P10 panels (a total of 6,144 SMD diodes), which are controlLED via a Wi-Fi network using the ESP32S module and an Android-based HTML application. The implementation allows public announcements, event schedules, and official notices to be updated quickly, accurately, and remotely. Testing results show that the connection between the ESP32S and LED P10 operates stably with an average display response time of 1.5 seconds, power consumption of 4.9VDC and 2.8–3A, and a maximum data transmission range of 15 meters. The system also proved reliable, with no connection interruptions or flickering during continuous operation. Therefore, the application of this IoT-based running text technology is considered effective and efficient in enhancing transparency, efficiency, and the digitalization of public information services within the Tanjungbalai City Government.
