Open Holder for nRF52-DK (PCA10040)

This simple yet robust holder secures your development board while maintaining full access to the connectors, micro-USB connector, buttons, and test points on the top side

Technical Details:

Screws: Designed for 5 M2x5 self-tapping countersunk screws

These are commonly found as "M2x5 self-tapping countersunk screws," often sold in sets of various sizes (Ali, Amazon, etc)

I chose this type of screw because they fit perfectly, do not protrude, are discreet, and sufficiently strong

Stability: A 6th mounting post is present near the antenna to serve only as a counter-support for the board

You can add 4 small anti-slip pads under the enclosure

CR2032 Battery Opening: The opening under the holder allows for battery extraction from the bottom (recent models)

Compatible with older board versions (side insertion), but requires unscrewing the board to change the battery
