Just Stack it !
The DEVCC Proto-Shield is now available and shown below is a fully assembled Proto-Shield in its natural environment, stacked with a DEVCC [V] board. Fully assembled, the Proto-Shield has a POT, Push Button and two LEDs.
As mentioned, the prototyping area is able to host new circuitry which can be soldered onto the PCB. Alternatively, a 170 tie point bread board can be adhered to the shield. If a bread board is added to the shield, the shield becomes reusable for new projects.
Seen directly from above as below, the shield has all PIN outs labelled and easily accessible.
All that remains is for you the hobbyist to get cracking with a project. The ProtoShield is available from Tindie.
