I2CMini: Low Cost USB to I2C Board for Quick Testing

I2CMini is a tiny USB to I2C Board designed and manufactured by Excamera Labs. It is a very useful tool for all embedded developers who are building products that has I2C devices and spend quite a lot of time evaluating them.

Evaluation phase is an important part for engineering design, tools which makes evaluation faster are always required.

As this tools works on PC, it is very easy to test I2C devices with a fraction of time without even writing a single line of code.

Your non-programmer engineering team members can help you evaluate I2C devices with this tool.

I2CMini uses FTDI USB-UART IC FT230X and Silicon Labs EFM8 an automotive grade 8-bit MCU for all the intelligent work like configurable I2C pullups, temperature sensing, detecting connected I2C device, etc.
