Here are some pictures of the result:
A general view of the PipZero on the cradle.
A left side view showing the power button. The reset button is on the opposite side.
A view from the back.
The lid is easy to open.
This is a prototype, so messy, but everything fits without squeezing. There is a RTC module and supercap for the lid closing glitch.
Size compared to the previous Pip4. How much smaller can this go?
