# MicArray UAC Drive Board (MA-USB8)
## Introduction
![](../../assets/modules/micarray_usbboard_bl616/product-front.png)
Driving a [microphone array module]((./micarray.md)), it provides UAC2.0 + CDC ACM + UART interfaces.
- UAC2.0: 8CH S16_LE 48000HZ
- CDC ACM: 16x16 Hotmap Frame
- UART: 16x16 Hotmap Frame on baudrate:2000000
### Hotmap Frame Format:
| frame| bytes | value |
|------|--------------|----------|
| head | 16 | 16x 0xFF |
| data | 16x16 (HxW) | ... |
## Connection
Choose one of the following connection methods:
- Preferred: USB <---> UAC2.0 + CDC ACM (Full functionality: obtain audio data and sound field map simultaneously)
- Or: UART/USB2TTL <---> UART (Limited performance scenarios, e.g., MCU: obtain sound field map only)
### Linux
![](../../assets/modules/micarray_usbboard_bl616/dmesg.png)
![](../../assets/modules/micarray_usbboard_bl616/lsusb.png)
### Windows
![](../../assets/modules/micarray_usbboard_bl616/devmgmt.png)
## Usage
### USB UAC2.0 (Audacity)
![](../../assets/modules/micarray_usbboard_bl616/audacity-linux-sine1k.png)
### USB CDC ACM RAW (Minicom) and USB2TTL UART HEX-CMAP (Picocom)
![](../../assets/modules/micarray_usbboard_bl616/minicom_acm&picocom_uart-combine.png)
### USB CDC ACM RAW (Minicom)
`minicom -D /dev/ttyACM0 -H`
![](../../assets/modules/micarray_usbboard_bl616/minicom_acm-raw.png)
### USB2TTL UART RAW (Minicom)
`minicom -D /dev/ttyUSB0 -b 2000000 -H`
![](../../assets/modules/micarray_usbboard_bl616/minicom_uart-raw.png)
### USB2TTL UART RAW,HEX-CMAP (Picocom)
1. `picocom -b 2000000 /dev/ttyUSB0`
![](../../assets/modules/micarray_usbboard_bl616/picocom_uart-raw-errcode.png)
2. type `F` and then `C`

<img src="../../assets/modules/micarray_usbboard_bl616/picocom_uart-hex-cmap.png" style="width: 45%;">
</div>
3. type `f`

## Commands
| Command | Input (Lower/Uppercase: Off/On) | Default | Remarks | Input Sources |
|--------------------------------------------------|---------------------------------|---------|----------------------------------------------|-----------------|
| Set UAC CH6 Beamforming Direction Angle | 0,1,..9,A,B | 0 | Actual angle = input value × 30 (0,1,..B => 0°,30°,...,330°). Corresponds to the clockwise direction starting from microphone 0, as per the [microphone array](./micarray.md). | Any |
| UART Sound Source Map Pseudocolor Mapping Toggle | c, C | c | Requires precondition: UART 16x16 sound source map printing enabled. | UART input only |
| UART Internal Debug Info Toggle | d, D | d | Controls internal debugging output. | UART input only |
| LED Real-Time Sound Direction Indicator Toggle | e, E | E | Controls LED indicators. | Any |
| UART 16x16 Sound Field Map Print Toggle | f, F | f | Toggles printing of 16x16 sound source map (ASCII). | UART input only |
| Restore Default Settings | R | \ |Restores a series of configurations to default values. | Any |
## Firmware
Download it from [here](../../assets/modules/micarray_usbboard_bl616/firmware/MA-USB8-250822.bin) and then refer to [this guide](../logic_analyzer/combo8/update_firmware.html#Burn-firmware) to update the firmware.

# 麦克风阵列UAC驱动板 MA-USB8
## 产品介绍
![](../../assets/modules/micarray_usbboard_bl616/product-front.png)
搭配麦克风阵列模块使用,提供 UAC2.0 + CDC ACM + UART 接口.
- UAC2.0: 8CH S16_LE 48000HZ
- CDC ACM: 16x16 Hotmap Frame
- UART: 16x16 Hotmap Frame on baudrate:2000000
### Hotmap Frame Format:
| frame| bytes | value |
|------|--------------|----------|
| head | 16 | 16x 0xFF |
| data | 16x16 (HxW) | ... |
## 硬件连接
以下连接方式选择其一即可:
- 首选 USB <---> UAC2.0 + CDC ACM (全量功能: 获取音频数据,同时获取声场图)
- 或 UART/USB2TTL <---> UART (有限性能场景如MCU: 仅获取声场图)
