Time saving embedded tools MCU Card MCU Card is a standardized add-on board, which allows very simple installation (and supply any of the supported MCUs on an appropriate MCU card, upon request. replacement) of the microcontroller unit (MCU) on a system equipped with the MCU Card Please visit www.mikroe.com/development-boards/mcu-cards for more information socket. Depending on the MCU type, its pin count, and the number of required external about the MCU Card support. components, there are several different MCU Cards for each MCU type. This makes each MCU Card a self-contained unit, allowing the development system to operate on a logic From the top side, each MCU Card has a clearly labeled MCU family it is designed for level, not having to facilitate specific requirements of many different MCUs. This also (MCU CARD for KINETIS, MCU CARD for STM32), as well as its PORT width, printed just allows the MCU to be freely chosen, regardless of the pin count or pin compatibility. Most below the MCU family label (8-BIT PORT, 16-BIT PORT, 32-BIT PORT). In addition, pins importantly, it allows to swap MCU Cards easily during the development phase, without are grouped in accordance to mikroBUS sockets to which they are routed. Therefore, any additional hardware interventions. there are 5 groups of pins. The pins labeled with yellow color belong to mikroBUS sockets, while the white labels represent corresponding pins on the MCU. On the bottom MCU Card is equipped with two 168-pin mezzanine connectors (one male and one side of the MCU Card, users can find the hardware revision number of the MCU Card female connector) with the standardized pinout. MCU Card is really easy to be installed itself, as well as the link to the www.mikroe.com web page. on a development board, featuring a smart design which minimizes any possibility of incorrect orientation and placement into the MCU Card socket. Find the standardized MCU Card pinout in the schematic printed on the back side. There are many pre-assembled MCU Cards equipped with the most commonly used MCUs in our shop already, with more being produced almost daily.
