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.
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.
