STEVAL-IDI001V1 is an evaluation board based on the STM32F4 Microcontroller and a wide range of ST sensors. With a small form factor (4 x 4 cm), it represents an integration of sensors and CPU for a "sensor hub like" application. The hardware is compatible with STM32Nucleo and X-NUCLEO expansion boards. The included adapter board is an expansion board that allows the interoperability between STEVAL-IDI001V1, STM32Nucleo and various X-NUCLEO expansions. Expansion boards can be connected either via Arduino or morpho connectors. The evaluation board comes with built-in data logging firmware. It allows streaming and storing of the selected sensor measurements via USB or via bluetooth low energy if an X-NUCLEO-IDB04A1 (or X-NUCLEO-IDB05A1) is plugged through the adapter board. The acquired data can be used to implement new advanced algorithms.
