I see adafruit sells the PA-09, PA-20, and PA-21 crimp tools from
Engineer. I'm very confused which tool is the proper one for my purposes. I
will mostly be crimping 2.54mm "dupont" breadboard style jumper connectors.
Which tool would do this job well and also have versatility for other connectors? I may be getting into RC in the
near future. I'm also curious if the blue ratcheting style crimpers would
perform better or worse?
