Proto Shield

The Proto Shield gives the OpenMV Cam a 10x10 through-hole prototyping area with 3.3 V and GND rails tied to the camera, plus broken-out I/O pins for soldering on custom circuits.

Highlights

  • 10x10 through-hole prototyping grid

  • 3.3 V and GND power rails tied to the OpenMV Cam

  • Broken-out OpenMV Cam I/O pins

  • Solder on accelerometers, sensors, or LED circuits

Pinout

Proto Shield Pinout

Every header pin is broken out unconnected to the prototyping grid for the user to wire as they like. The 3.3 V and GND rails are tied through to the camera so soldered-on circuits can be powered directly.

Usage

Whatever you wire to the prototyping grid is driven through whichever peripheral API fits — GPIO, PWM, ADC, I²C, SPI, UART, and so on. As a simple example, blink an LED soldered to one of the broken-out I/O pads:

from machine import Pin
import time

led = Pin("P0", Pin.OUT)
while True:
    led.on()
    time.sleep_ms(500)
    led.off()
    time.sleep_ms(500)
