Hello Ganesan, Welcome! I hope you enjoy the place as much as we do! Scott

Fit in the 2.54mm female headers? For that, I some times use male 2.54mm break-offs and do the same HS job. Some of the ones pictured are that way.

The new Naan boards are in! The latest to the Naan proto line: Both of these are single-sided and can be panelized at a small extra cost. I go...

@raven1152 BTW, if you are in the USA, there is a good deal to be had on a NEW Meanwell PSU in closeouts. Let me know and I can send the info to you...
