RGB Matrix HUB75 S3 LED Controller Board with Audio and SD Slot | HUB75 RGB LED matrix controller with Type-C power, microSD storage, audio codec, microphones and RTC interface

Overview The RGB Matrix HUB75 S3 is a multifunctional RGB LED matrix controller board designed for HUB75 LED matrix display projects, embedded development, creative display control and interactive electronics applications. It can directly connect to HUB75 RGB LED matrices and control text, images, animations, clocks, status information and custom visual content. This HUB75 controller board provides two
HUB75 interface options: one for ribbon cable connection and one for direct plug-in connection. Dual Type-C ports are provided for board power, program download/debugging and dedicated matrix power input, while the VH-4P terminal supports 5V power connection for RGB LED matrix panels. For local content storage, the onboard microSD slot can store images, audio files and project resources, enabling offline display playback and local data logging. The onboard ES7210 audio ADC and ES8311 audio codec, together with dual silicon microphones and speaker interface, support audio input, audio output and voice interaction development. The board also includes an RTC timekeeping interface, I2C expansion interface, 3-way thumb wheel switch, EN/BOOT controls and reserved debug pins such as TXD, RXD, IO45, IO46, RST and BOOT. These interfaces help users perform firmware download, serial debugging, function expansion and system integration. This product is a development controller board for HUB75 RGB LED matrix projects. RGB matrix panel, speaker, microSD card, power adapter and external accessories are not included.
