## Description

USB to I2C module with CP2112 for debugging and quickly connecting SMBus/I2C devices to a PC, ideal for testing and applications such as DJI battery diagnostics. It offers full speed USB 2.0, easy GUI configuration without complex firmware or drivers, 8 configurable GPIO pins, and direct USB power with internal regulator for stable operation on Windows, Mac, and Linux.
CP2112 controller module for connecting USB devices to SMBus/I2C, offering the ability to create applications quickly and efficiently. This module integrates a complete USB 2.0 full-speed controller, a USB transceiver oscillator, and 8 configurable GPI0 pins, providing a high degree of customization. Thanks to the simple GUI interface, configuration and customization can be done without the need to develop complex firmware or drivers, enabling a fast USB connection with minimal development effort.
The CP2112 controller provides a complete and integrated solution for connecting USB devices to SMBus, powered via the USB bus with a voltage range between 4.0 and 5.25V. It operates efficiently across a wide temperature range, from -40°C to 85°C, making it ideal for various operating environments. It features an integrated reset circuit and an internal 3.45V voltage regulator, ensuring stability and performance.
With a 512-byte SMBus buffer and configurable 7-bit addresses for slave devices, CP2112 allows efficient data storage and management. It also supports USB suspend for power saving and offers 8 configurable GPIO pins for multiple input and output options.
It is compatible with Windows, Mac, and Linux systems, with easy integration.
The integrated LEDs display operation on the I2C bus.
When connected to a PC, the CP2112 module does not appear as a COM port, but as a USB HID device, more specifically "USB Input Device" in the "Human Interface Devices" section of "Device Manager".
