Includes 40 pins, which is enough to socket one nice!nano with excess left over.

This tradition machine pin socket allows you to socket a nice!nano (or other Pro Micro) so that you can easily debug your keyboard, get access to your battery, or replace the microcontroller unit itself.

These sockets are raised  ~4.7mm off of the PCB, which give a battery clearance of ~4.7mm with the nice!nano flipped upright and ~3.1mm when the nice!nano is socketed upside down, which is the perfect clearance to fit a 301230 battery underneath.

Note: This does not work with traditional square post headers, (like ones included with the nice!nano) and it requires diode legs or Mill-Max socket legs to install properly.
