X-NUCLEO-IKA01A1 Multifunctional board based on operational amplifiers.

The X-NUCLEO-IKA01A1 is a multifunctional expansion board based on STMicroelectronics operational amplifiers. It provides an affordable and easy-to-use solution for various use cases with your STM32 Nucleo board.
The X-NUCLEO-IKA01A1 is compatible with the Arduino™ UNO R3 connector, and supports the addition of other boards that can be stacked for enhanced applications with an STM32 Nucleo board.
It can be used as an analog front-end by conditioning signals as actuator to drive LEDs or coils, or in a comparator architecture.

Thanks to its current-sensing configuration, it allows current measurement of any device that has a Micro-USB port. A highly accurate TSZ124 Micropower operational amplifier is used for this configuration as well as for that of the instrumentation amplifier. The expansion board also contains a TSU104 Nanopower op-amp and a TSV734 Micropower op-amp for mobile applications.
