评估板MAX32660 EVK

The MAX32660 evaluation kit provides a compact devel­opment platform that provides access to all the features of the MAX32660 in a tiny, easy to use board. The form factor is a small 0.6in by 0.9in dual-row header footprint that is compatible with breadboards. The board includes a 10-pin Arm® Cortex® debug connector so that it can be used with a DAPLink adapter. Additionally, a red LED indi­cator and a pushbutton are on board. This board provides a powerful processing subsystem in a very small space that can be easily integrated into a variety of applications.
