Getting started with the multifunctional expansion board based on
operational amplifiers for STM32 Nucleo
Introduction
The X-NUCLEO-IKA01A1 is a multifunctional expansion board based on operational
amplifiers. It provides an easy-to-use and affordable solution for different multifunctional 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 expansion board. It can be used
as a analog front-end by conditioning signals as an actuator to drive LED or coils, or in a
comparator architecture. Thanks to its current-sensing configuration, it allows current
measurement of any device that has a USB port. For this configuration and the
instrumentation amplifier configuration, a highly accurate operational amplifier (TSZ124) is
used. The expansion board also contains Nanopower (TSU104) and Micropower (TSV734)
operational amplifiers for mobile applications.
This user manual describes how to use the predefined configurations of the X-NUCLEO-
IKA01A1 expansion board:
• Instrumentation amplifier structure
• Current sensing with or without USB port
• Photodiode/UV current sensing
• Buffer
• Full wave rectifier
• Constant current LED driver
• Window comparator
The expansion board is also equipped with one prototyping area is powered through the
Arduino UNO R3 connectors.
