🎯 Key Advantages Over Commercial Streamers

Critical Safety First: Electrical & Handling Precautions

Before touching any components, internalize these non-negotiable safety rules:

⚠️ Electrical Safety Rules

1. Power Supply Voltage: Use only 5.1V/3A official Raspberry Pi power supplies. Higher voltage WILL permanently damage your Pi (instant death). Lower voltage causes instability and SD card corruption.

2. Static Electricity: Always ground yourself before handling the Raspberry Pi board or DAC HAT. A simple static discharge can fry the CPU. Use an anti-static wrist strap or touch a grounded metal object.

3. DAC HAT Installation: POWER OFF the Raspberry Pi completely before attaching or removing any HAT boards. Hot-plugging can destroy both the Pi and DAC.

4. USB HDD/SSD Power: External drives MUST be self-powered or connected via a powered USB hub. The Pi's USB ports cannot reliably power 2.5" drives, causing brownouts and data loss.

5. Ventilation: The Raspberry Pi 4 runs hot. Always use a case with active cooling (fan) or excellent passive ventilation when running 24/7. Extended overheating (>80°C) throttles performance and shortens lifespan.

🔧 Physical Handling Safety

• SD Card Insertion: Push gently until you hear a soft click. Forcing it can break the spring mechanism.
• GPIO Pins: Never short-circuit GPIO pins with metal objects. Use plastic spacers when mounting HATs.
• Cable Management: Secure all cables to prevent strain on ports. A yanked USB cable can rip the surface-mount connector off the board.
• Touchscreen Installation: When connecting DSI ribbon cables, lift the locking tab gently. The connectors are fragile and expensive to replace.

Pro Safety Tip: Invest $10 in a quality surge protector. Raspberry Pis have zero built-in surge protection, and a power spike will turn your streamer into a paperweight.

Complete Hardware Shopping List: Two Build Options

💰 Budget Build: The "Jukebox Revival" ($85-95)

Perfect for converting old powered speakers or a vintage amplifier into a wireless streaming system.

🎧 Audiophile Build: The "Reference Streamer" ($180-220)

Competes with streamers costing $3,000+. Features premium DAC and linear power supply.

🛒 Where to Buy (Avoid Counterfeits):

• Official: RaspberryPi.com, PiHut, Adafruit
• DAC HATs: IQAudio.co.uk, HiFiBerry.com, Allo.com
• Europe: Audiophonics.fr (best selection, fair pricing)
• NEVER buy Pis from Amazon/eBay unless sold by official retailers (90% are fakes or used boards repackaged as new).

Step-by-Step BerryAudio Installation Guide

Step 0: Prepare Your MicroSD Card (Critical)

Safety Note: Flashing an image erases ALL data on the card. Backup important files first.

1. Download the BerryAudio v1.1.0 image from berryaudio.org

3. Connect audio cables:

   • Analog: 3.5mm to RCA into your amplifier's AUX input
   • Digital: If using USB DAC, connect now (hot-plugging USB is safe)
   • I2S DAC: Already connected via GPIO

4. Attach cooling: Install fan to 5V/GND pins or attach heatsink to CPU/RAM

Step 2: First Boot & Network Setup

1. Connect power cable LAST. The Pi will boot automatically.
2. WAIT 3-5 minutes for first-boot initialization. The LED should blink, then go solid.
3. On your phone/laptop, search for WiFi network BerryAudio-xxxx
4. Connect to it (password: berryaudio)
5. Your browser should auto-open the setup wizard. If not, go to http://192.168.50.1
