The board has been developed to interface sensors with an Android device. By the USB port the Android mobile or tablet or pc set the device as slave by the OTG mode. The board can be powered both from the Android device or by its power supply at 5V and borderline cases are considered. The configuration can be set as slave by device and master by host wherever used usb devices. The connectors on the board permit to interface sensors by I2C signals, NTC temperature sensors, encoder and load cells for several use cases, SPI interface is also available. The module is powered by the famous STM32F100 serie and the firmware can be customized upon request. The CPU can be also programmed by Arduino in order to simplify testing and programming. The cases can be purchased separately upon requests. 3D design is available.
