1. Core Specifications (Overview)

1.1 8748 Form Factor

An electromechanical co-design standard ensuring seamless dimensional alignment between PCB CAD (mil-based) and mechanical enclosure fabrication (mm-based), reducing conversion errors to <15 µm.

• Dimensions: 87.0 mm × 48.0 mm (3425 mil × 1890 mil)
• Mounting Pitch: 77.0 mm × 38.0 mm (3031 mil × 1496 mil), M3 screws (Φ3.3 mm)
• Full Specification: English (docs/en/8748_formfactor.md) | 日本語 (docs/ja/8748_formfactor.md)

1.2 ADX Pinout

A 20-pin unified expansion interface (2×10-pin, 2.54 mm pitch) featuring GND shielding and static control lines for noise isolation across SPI, I2C, UART, and analog signals.

• Connector: 2×10-pin 2.54 mm pitch header (CN2)
• Full Specification: English (docs/en/ADX_pinout.md) | 日本語 (docs/ja/ADX_pinout.md)
