The SiBRAIN For ATMEGA6450 is a standardized microcontroller add-on board, which allows straightforward installation and replacement of the microcontroller unit (MCU) on a development board equipped with the SiBRAIN Card socket. By introducing the new SiBRAIN standard, we have ensured absolute compatibility between the development board and any of the supported MCUs, regardless of their pin number and compatibility. SiBRAIN has two 168-pin mezzanine connectors, allowing it to support even MCUs with a high pin count. The clever design allows effortless usage, following the well-established plug & play concept of the Click board™ line of products.
