SupTronics X1300-A2 I2S Audio Accessory

The SupTronics X1300-A2 I2S Audio Add-on enables HDMI audio capture when used with the X1300 or X630 bridge boards. It connects via I2S, preserves airflow for active cooling, includes GPIO passthrough, and supports HDMI detection, reset, and interrupts.

---

The SupTronics X1300-A2 is an I2S audio accessory board designed for the SupTronics X1300 and X630 HDMI to CSI boards, enabling HDMI audio capture through the I2S interface.

It is specifically designed to be placed on top of the Raspberry Pi, similar to a traditional HAT, and provides a 40-pin header for easy access to the GPIO.

The board shape keeps it out of the way of an active cooler, to ensure airflow to the CPU is maintained.

Raspberry Pi, Active Cooler and X1300/X630 board not included. An X1300/X630 board is required to use this product.
