The USB firmware is designed for use with host operating systems such as **Windows, Linux, and macOS** when communicating through the USB hardware interface.
208
+
209
+
Two firmware variants are available: **respeaker_xvf3800_usb_dfu_firmware_v2.0.x.bin**, which provides **2-channel** audio, and **respeaker_xvf3800_usb_dfu_firmware_6chl_v2.0.x.bin**, which provides **6-channel** audio. Both firmware versions operate at a **16 kHz** sampling rate with **32-bit** depth.

The I2S firmware is intended for use when the device is connected to a microcontroller host such as the **XIAO ESP32S3**. In this configuration, voice data is transmitted using the I2S protocol.
226
+
227
+
The firmware file **respeaker_xvf3800_i2s_dfu_firmware_v1.0.x.bin** is available in [here](https://github.com/respeaker/reSpeaker_XVF3800_USB_4MIC_ARRAY/tree/master/xmos_firmwares/i2s). This firmware supports **2-channel** audio with a **32-bit** depth.
The Home Assistant firmware is another I2S-based firmware specifically designed for integration with Home Assistant. This optimized firmware uses 2-channel audio with a 48 kHz sampling rate, providing better compatibility and performance within the Home Assistant environment.
