Analogue development kits are circuit boards that come pre-built with various components and modules for different projects. Their typical applications are to make it easier to achieve an end result. They have a wide variety of uses and purposes. A development kit can also be called an evaluation board. Audio analogue development kits generally come with a 3.5mm headphone jack to allow the user to listen to what is playing on the board as well as onboard storage to store files.What can I do with an analogue development kit?Add sounds or music to your designLearn about the relationship between current, voltage and impedanceMeasure the presence and position of a conductive target object. Research, development and testing of specific components. Convert analogue audio into digital signals.Amplify signal What types of analogue kits are there?Arduino add-on boards Audio conversion boards – converting, playing and testing audioMicrophone boards – small microphones the enhance your project Data loggers – Measure current, voltage, resistance & other data.Active filter boards – Add daughter boards and connect multiple boards for a better result. Development kits, evaluations boards and starter kits are available from a wide range of supplies such as RS Pro, Analog Devices STMicroelectronics, Silicon Labs, ROHM, MikroElektronika, Microchip and Korg Nutube. Many development kits need software to run. The software is usually free and downloadable from the respective brand.
