IO-Module Prototype #002 Testing

Okay, so I got the latest prototype PCB for the IO-Module... time to build prototype #002.

I usually build 2 to 5 prototypes before the kit goes on sale. I want to make sure that it works, that everything works right and performs great, easy to assemble, the parts list correct and all that. It's the DETAILS that matter!

Some pics...

Since the PCBs are prototype, there are no cutouts for the transformers. On the final production PCB, the holes will be cutout by the factory.

So we drill some 3/8" holes on each corner of the square cutout.

And here's a pic of the drilled PCB.

Using a jig saw, we do a rough cut of the square hole... then use a file to smoothen the edges.

Next, we test fit our transformer (Cinemag CMOQ-2S) into the PCB... fits perfectly on the 1st try!

Here's the bottom view.

And a photo showing both the input and output transformers.
