# Bill of materials In this module we will use the following components: * [STM32 NUCLEO-F072RB](https://www.st.com/en/evaluation-tools/nucleo-f072rb.html) * [USB cable - 6" A/MiniB](https://www.adafruit.com/product/899) * [Adafruit I2S MEMS Microphone Breakout](https://www.adafruit.com/product/3421) * [Adafruit I2S Stereo Decoder](https://www.adafruit.com/product/3678) * [Jumper Wires](https://www.adafruit.com/product/266) In principle, any board from STM32 can be used for these exercises, as long as it is supported by [STM32CubeIDE](https://www.st.com/en/development-tools/stm32cubeide.html), and exposes at least *two* I2S buses since both the microphone and the DAC (Stereo Decoder) require a dedicated I2S bus for audio transfers. ## Prerequisites * basic knowledge of C and Python programming * a PC with a USB port (the microcontroller will be programmed and powered by your PC via a USB cable) * and, of course, having completed the the previous DSP modules! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://hwlab.learndsp.org/bill-of-materials.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
