HP-01 Next step done!

I want to give you some news about the progress of the HP-01 repair kit.

When I created this thread I had only the concept in mind. From concept to finished product is a long way. Now I finished the schematic and layout and I will give it to the manufacturer for making some first prototype boards.

The new HP-01 replacement circuit contains both, the hybrid ceramic main board and the keyboard. The original keyboard could have been reused, but then you had to separate it from the main board, which is not easy. The new keyboard will have the same gold contacts as the old one and I made the layout identical to the original.



The board size is only 32x20 mm, red is top layer, blue is bottom layer.

So far! I hope the next step will be to show you an image of the first LED light of the new HP-01
