Support Windows, Linux, MAC OS. Support Android and Raspberry Pi. USB bus power supply without external power; 5V and 3.3V output; max current 500mA; short circuit protection. Support I2C Host/Master mode and Slave mode. 2 channels Hard(standard) mode up to 1.2M. 8 channels GPIO mode up to 400K. Support PMBus and SMBus and provide the API library. There is much kinds of free PC software compatible with the LabviEW interface to deal with different requirement. Support USB-SDI12, USB-EasyScale, USB-UART and counter, PWM output, ADC sampling, GPIO control and other functions. Multiple USB-I2C adapter can work in one PC at the same time (up to 100). It can output the RS485 signal (DE) and realize USB-RS485 by a TTL-RS485 module. The firmware can free update or change (such as SPI) by Own Bootloader program. Provide secondary development API and API detailed document and all kinds of languages platform application examples (Labview,C ,VC,Qt,Python,Labwindows/CVI,C++ Builder,VB,VB.NET,Delphi,CodeBlocks,GCC,Eclipse,Android Studio etc.).
