 Hello, and welcome to this video explaining how to get started with the STM32 Nucleo Multifunctional Op-Amp Expansion Board. This board is part of the STM32 Open Development Environment, a fast and affordable way to develop innovative devices and applications with ST components. Information on how to obtain the board can be found on www.st.com.xnucleo. Consider the reference XNucleo IKA01A1. The board contains seven predefined configurations based on three different operational amplifiers, a TSZ-124 for instrumentation amplifier and current sensing configurations, a TSU-104 for window comparator function and photodiode or UV sensor configurations, and a TSV-734 for LED driver and buffer configurations. The board is equipped with an Arduino Uno R3 connector, allowing it to be plugged into an STM32 Nucleo Development Board. First, connect the STM32 Nucleo Development Board to a PC using a mini USB cable. The board is automatically detected and seen as a disk drive. Visit ST.com in search for the keyword XNucleo IKA01A1. Click on the main part number link, then go to the Tools and Software section and click on the XCube link. Finally, go to the end of the page and click on the download button in the Get Software section. Now, let's try a sample application that allows you to use the various operational amplifiers on the expansion board. The firmware to be installed is called Op-Amp and can be found in the example folder of the project's directory as shown here. Select the STM32 Nucleo Development Board you are using and drag and drop the binary file onto the Nucleo disk drive. The user can interact with the expansion board in real time through a virtual COM port using a terminal application configured at 9600 BOD. Once the firmware is uploaded, the terminal window displays the values of various output parameters read from the board, such as current sensing output, window comparator states, photodiode output voltage, LED driver duty cycle, etc. A comprehensive set of documentation for the multifunctional Op-Amp expansion board, including a user manual, application notes, quick start guide, and data sheet is also available.
