3 SWCLK Digital In nRF52480 Single Wire Debug Clock
5 GND Power Power Ground
6 RST Digital In Active low reset input
5 Mechanical Information
5.1 Board Outline and Mounting Holes
The board measures are mixed between metric and imperial. Imperial measures are used to maintain a 100 mil
pitch grid between pin rows to allow them to fit a breadboard whereas board length is Metric.
