## Description

I²CMini is an easy-to-use, open-source tool for controlling I²C devices over USB, 100% compatible with I²CDriver. Its a small friend that will make working with I2C a breeze, especially if they have a Qwiic/Stemma QT or even Grove I2C connector! USB to I²C interface in a tiny 18x18mm board Can act as a I²C controller, passive monitor, and capture-to-PC supported at 400 kHz Two I²C ports: one on 0.1" header; one Qwiic/Stemma QT Supplied with 100mm Qwiic/Stemma QT to socket jumper set Flexible control: GUI, command-line, C/C++, and Python 2/3 host software provided for Windows, Mac, and Linux It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. The board includes a separate 3.3 V supply, on-chip temperature monitoring, and programmable pull-ups for both I²C lines. I²CMini is particularly well-suited for applications like IoT and drones, cleanly separating your SBC from the I²C bus. Because it is totally compatible with I²CDriver, you can develop on the I²CDriver and deploy on the I²CMini. Like I²CDriver, it works equally well with Windows, Mac, and Linux. It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. The board includes a separate 3.3 V supply for your I²C sensors and peripherals. On the I²C side, I²CMini has the same four-pin header for connecting to peripherals as the I²CDriver. You can solder directly to this .1" header, and because it is castellated, you can use I²CMini as a module to add instant USB access to an I²C subsystem. By controlling I²C hardware using the PC tools you're most comfortable with, you can get devices doing what you want in a fraction of the development time. Calibrating devices like accelerometers, magnetometers, and gyroscopes is much easier when done directly on the PC. I²CMini has a Sparkfun Qwiic STEMMA QT-compatible connector so any of our QT sensors or devices can be plugged right in with no soldering. You can also use a QT-to-Grove adapter cable to use Grove I2C devices I²CMini comes with free software to control it from: a GUI the command-line C and C++ using a single source file Python 2 and 3, using a module Like I²CDriver, it can both drive and listen on the I²C bus, and it has the same programmable pull-up resistors for both I²C lines.
