VEX EDR or Lego EV3 for high school robotics elective?

[Dave Campbell]

Remove the wires from the plastic housing, cut wires, re-crimp new pins on the wires, then put back into the plastic housing.
On the 3-wire connectors, I have my students just cut the ends of PWM wires and solder new connectors onto the VEX parts. Good experience for them to learn to solder and use heat shrink tubing for a clean finished look. Can be expensive replacing PWM wires, so I have ordered more pins and housings from Digi-Key (thanks to the FRC Digi-Key voucher)

I'll look for part numbers for the pins and housings once I am back in my lab and post for your reference...
