M20 connector parts
24 sets of 2.54 mm M20 housings and pin-grasping ports to match. This is enough for a v0.6.0 Concertina. v0.7.0 needs 2 more sets (total: 26) for an optional hardware reset button. Regardless of what you’re building with these, you need suitable crimping pliers and probably a few spares.
Prefer combined housings of 2/4/8 sockets instead of single housings like these.
