mbed library for STMicroelectronics' X-NUCLEO-IKA01A1 expansion board.





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.

Key Features:

  • 7 predefined configurations:
  • Instrumentation amplifier structure
  • Current sensing with or without USB
  • Photodiode/ultraviolet (UV) current sensing
  • Buffer
  • Full wave rectifier
  • Constant current LED driver
  • Window comparator
  • One prototyping area
  • Compatible with STM32 Nucleo boards
  • Comprehensive free development firmware library (X-CUBE-ANALOG1)
  • Powered through the Arduino UNO connectors
  • RoHS compliant
