The Proto Shield gives you the ability to easily extend your OpenMV Cam's functionality. It features a 10x10 through-hole prototyping area with a 3.3V rail and a GND rail that are connected to your OpenMV Cam's 3.3V rail and GND rail. The rest of the I/O pins are left unconnected to let you build what you want.
Need to add an accelerometer board to your OpenMV Cam? Or any other sensor board? You can easily solder these onto the Proto Shield so you can use them with your OpenMV Cam on-the-go. Or, do you need more illumination? Then build a more powerful LED circuit on a Proto Shield for your OpenMV Cam. With the Proto Shield you can extend your OpenMV Cam's functionality how you want.
