Over the years we've built many prototypes. This week when starting yet another it became obvious to there was a lot of repeated work in assembling each prototype. Each of the prototypes needed a voltage regulator, reset chip, RS232 level shifters, watch dog, etc.

Instead of making yet another prototype with these functions I assembled a small daughterboard with three 5 pin headers that contained all of the often needed building blocks. Now when we need a new prototype we simply solder a few header pins to the new prototype and plug in the daughterboard. This saves quite a bit of time and we know that the functions on the daughterboard already work and don't have to be tested.



The only circuitry that needs to be assembled now is the extra external circuitry required for the new product.

Hope this is useful for some of you.

Cheers,

Bert
