The board has a lot of un used space, which can be used for adding some features.

I asked for feedback on two facebook groups here and here.

I got some good suggestions and spotted some my mistakes as well.

Here are the features I'm adding now.

1. Fliping the switches so legends are visible during prototyping.

2. Re position the mount holes.

3. Add bi-directional 3v3 to 5v level conversion on board so 5v devices and be easily be interfaced.

4. Removing the 6 pin header that connects to internal flash
