Reply To: Connectors for 20-pin headers

Home Forums Mayfly Data Logger Connectors for 20-pin headers Reply To: Connectors for 20-pin headers


    I’ve got a lot of my prototype wires and headers at SparkFun and Adafruit.  They both have pages and pages of connectors for the final product.

    I have been buying a couple of each of the Mayfly add-ons when I see them in stock so I have them when I need them.  I have two mayfly proto boards and will probably just need one.  Let me know if you get in a bind.

    SparkFun has all kinds of headers since most of their products come minus headers.  The soldering was a little intimidating at first.  Once you learn to time the heat up of each connection (I just count) they come out pretty good.  I have a 10x loupe from my engineering days that I go over them with under a good light for quality control.  That has saved me a lot of head scratching.
