使用DACBERRY 400添加音频插孔到Raspberry Pi 400

覆盆子皮400是一台具有Raspberry Pi 4 SBC功能的键盘PC,其中之一是缺少AV端口。但是现在,您可以通过连接到40针GPIO标头的DACBERRY 400 S扩展板向Raspberry Pi 400添加3.5毫米音频插孔。

这是一种更整洁的方式cheap USB audio donglewith microphone and headphone jacks, as it takes less space, and does not occupy any of the USB ports from the Raspberry Pi 400, and it does not prevent you from using the GPIO header. It’s also better suited for headphones with both microphone input and analog stereo audio output into a single jack, and probably comes with better audio quality than the low-cost USB dongles.

音频Jack Raspberry Pi 400 DACBERRY 400 s(DBR400S)规格:

  • 镀金的3.5毫米耳机/耳机插孔(麦克风in - 立体声)
  • DAC SNR 102dB @ 96kHz
  • ADC SNR 92dB @ 96kHz
  • THD+N 0.003% / -92dB @ 1kHz
  • 具有3D效果的集成DSP,EQ和De-emphoist
  • 超低噪声LDO用于模拟动力导轨
  • Signals from GPIO header – I2C, PCM, 5V, GND (See pinout diagram below)
  • Low-Noise design with isolated Digital and Analog parts
  • 电源 - 直接来自GPIO标头的5V
  • 维度 - 77 x 20 x 15毫米
  • 重量 - 30克
  • 兼容性 - Raspberry Pi 400,并带有40针GPIO连接器,包括Raspberry Pi,Asus Tinker Board,Odroid-C4等…

DACBerry 400 GPIO pinout
这maker of the board, Spain-based DSA Electronics, says the DACBerry 400 S is compatible withOSMC,runeaudio,,Moode,PicorePlayer,Pimusicbox,OpenELEC,以及其他音频程序,这意味着它可能是软件敏捷的……您​​只需要在Raspberry Pi OS或其他支持的操作系统中运行以下脚本以安装:


A closer look at the board reveals there’s also a DACBerry 400 M model as well, which adds an extra 4-pole CTIA audio jack for stereo input. A入门指南shows how to record audio with Audacity, after running the installation script.

DACBERRY 400 S vs DACBERRY 400 M 这DACBerry 400 S is currently出售19.95欧元,但我还找不到待售的M模型。这比低成本USB音频加密狗贵得多价格低于$ 5,,,,so it’s up to you if the space saved, and potentially higher audio quality warrant the higher price tag.

Guess I am being a party pooper but what about those HDMI to HDMI splitters with audio/headphones out. They have been around for ages ?

Also does the display you are using have a audio jack.

我想这不是RPI粉丝喜欢的方式。您需要有一个gpio扩展板的宝塔伸出背部,以便能够将自己视为真正的RPI粉丝。

I had a great laugh reading this You forgot also a large amount of unused “just in case” modules in your drawer!

While I understand that research, development and support has it’s cost, I think that this piece of hardware is a bit overpriced for electronics that can be built with nearly 10 euros buying parts with single piece consumer pices. Despite this, it’s a very elegant solution.

Ah, the old “curl piped into bash” install method.

我确实需要创建一个像这样工作的假项目,并在计算机上安装rootkit,以便这种练习停止。但这甚至不确定会改变任何东西

Do you really fear a script somewhere sitting on the Internet you can read beforehand? What about all those crappy OS images supplied by companies or hobbyists that are downloaded by millions of SBC/ARM users without giving a f*ck every other day? If these OS images aren’t generated from scratch but manually assembled all this ‘curl piped into bash’ stuff might’ve already happened multiple times…

不同之处在于,我不在乎当这种命令导致毁了 *他们 *的开发机或仅仅是他们的图像。我确实在乎它何时会毁了我的。是的,在从Github挑选脚本之前,我确实阅读了它,如果它完全不可读取,我不会启动它,因为通常可以很好地表明作者不知道它的作用。无论如何,我不会在苏多(Sudo)下运行它们。我并不特别担心他们隐藏的令人讨厌的事情,主要是同事过去犯的基本错误:dir = $(ls results*)rm -rf“ $ dir”/ thatRead more »

Why focussing on you as an expert? This here is about a hardware add-on that obviously needs some software adjustments too. There are 4 ways to achieve the latter: 1) write a tutorial with shell commands 2) put script available via https:// –> pipe into bash 3) provide a clickable application wrapper doing the very same 4) provide a modified OS/Raspbian image containing the mod 1) apparently doesn’t work for vast majority of SBC users (or Linux users in general). 2) is the best option since allowing experienced users to inspect the stuff they’re about to execute. Both 3) andRead more »

So what? Please remember we’re talking about the RPi/ARM world here where it’s ‘common sense’ to download whole OS images from somewhere on the Internet nobody has any change to really audit.
这些操作系统的图像主要是由甚至无法拼写“安全性”一词的人制作的,而诸如“卷发为bash”之类的东西可能已经发生了多次。

这“modern” internet owes a huge apology to Microsoft and ActiveX.
