USB 2.0 to I2C Bridge Module

A professional-grade CP2112-based USB-to-I²C/SMBus debug interface designed for engineers and developers working with sensor networks, embedded peripherals, and low-level protocol validation. Constructed with plastic and metal housing for mechanical integrity and partial EMI shielding. Operates from USB bus power (4.0–5.25 V) or external supply (3.0–3.6 V), with I/O voltage tolerance from 1.8 V. Features include USB 2.0 Full-Speed (12 Mbps) compliance, integrated reset circuit, 3.45 V voltage regulator, and support for USB suspend state. On-chip 194-byte OTP memory stores custom device descriptors, while 512-byte SMBus buffer allows high-throughput transaction handling. Clock speed and 7-bit slave address are fully configurable. Eight GPIOs support input/output and open-drain/push-pull configurations, plus a programmable clock output spanning 48 MHz to 94 kHz. Native compatibility with Windows, macOS and Linux HID-to-SMBus libraries enables immediate integration into Python, C/C++, or Node.js applications. Target use cases include portable instrumentation, USB-based sensor loggers, and lab-grade I²C protocol analysis. Operational temperature range: -40°C to +85°C.
