BY-3200S MacBook Logic Board Boot Power Cable

The BAIYI BY-3200S is an upgraded professional MacBook logic board startup power cable designed for 2008–2023 MacBooks. Featuring a real-time digital voltage and current display, dual power input modes (20A DC banana plug or 87W–140W Type-C fast charger), and built-in L-head, T-head, and Type-C connectors, it enables battery-free single-board booting and precise motherboard power fault diagnosis.

Key Features

• Real-Time Voltage & Current Display: Integrated dual-color digital display monitors real-time motherboard operating voltage and current draw.
• Automatic Board Sensing: Display remains off by default and automatically activates upon detecting a connected logic board.
• Multi-Function Power Switch: One-press toggle for digital display on/off; long-press (3–5s) to shut down or restore power input safely.
• Dual Input Options: Supports standard DC bench power supply (20V–21V / 20A max) or direct 87W–140W Type-C charger input for ultimate benchtop portability.
• Expanded Type-C Output: Integrated Type-C output port alongside native output cables for versatile diagnostic connections.
• Single-Board Boot Without Battery: Resolves no-boot failures caused by low BATLOW# signals, allowing single logic boards to boot straight into macOS without a connected battery.
