USB to TTL Serial Replacement Parts

Post by alienbike »

We have dozens of the Adafruit USB to TTL serial adapters with the Dupont connector. The issue is that after years of use, we are starting to see some broken wires. We need a source for the crimp pins so that we can repair these. I would prefer not to replace the whole connector if the problem is only a single broken wire.

@alienbike,

That you for including the digikey part# for the crimp pin. I think this will be helpful to others.

Did you also use a special crimp tool or just pinch down with plyers?

I use a generic crimper. It has five different dies for various crimps. Purchased on Amazon as Engineer PA-09.
