adapted a stripboard PCB with Nano to take a NRF24L10
if pins are adjacent it is possible to cut the stripboard tracks, e.g.
with tracks close together and cutting tracks between adjacent pins it is easy when soldering to short circuit tracks, etc - testing for continuity and short circuits using a multi-meter is essential
