Drawing the pushbutton in Inkscape is pretty straightforward. We are going to draw a top-view illustration of the button and its four metal leads that connect it to other parts, as follows: 12×12mm dark gray rectangle for the plastic case, with slightly rounded corners to make it softer....
The Esplora is supplied with four pushbuttons, a switch-type joystick, and a micro USB connector. Four mounting holes are available to affix the board to a chassis or panel. The Esplora PCB dimensions are shown in Figure 4-13. Arduino Pinout Configurations When creating a shield board for ...
