　　XMC4200数字电源控制卡

　　The XMC4200 Digital Power Control Card is an evaluation board with the goal to help engineers in the learning and testing of digital power control applications. The board features a XMC4200 microcontroller based on ARM® Cortex™M4F core.

　　The dimensions of the board (50 mm height, 45 mm width to connector) allow the usage of this evaluation card into designs with high requirements on power density. In particular dimensions of XMC4200 Digital Power Control Card are suitable for 1U rack designs. The control card integrates an isolated on board debugger for plug and play experience. The isolated debugger part can be detached once the code is finalized.

　　This board has been developed with the collaboration of WürthElektronik whose passive components and mechanical components are used.
