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)
