Description

ArduCAM Multi-Camera Adapter Board for Raspberry Pi:

The Raspberry Pi multi camera adapter module is a shield designed for connecting more than one camera to a single CSI camera port on Raspberry Pi A/B/B+ or Pi 2 board. One adapter board can connect four Raspberry Pi cameras – both OV5647 V1 and IMX219 V2. A limited stock of the original adapter are available at a reduced price. Stack up to a maximum of four adapter boards, which means you can have up to 16 cameras on a single Raspberry Pi board. See Pin Configuration and Operation sections below for more information.

Note: The Raspberry Pi multi camera adapter board is a nascent product that may have some stability issues and limitations because of the cable’s signal integrity and Raspberry Pi’s closed source video core libraries, so use it at your own risk.

Features:
  • Accommodate 4 Raspberry Pi cameras on a single multi-camera adapter board
  • Stackable up to 4 adapter boards
  • 3 GPIOs required for multiplexing on one adapter board, 5 GPIOs for two adapter board, 9 GPIOs for four adapter board
  • All camera ports use FFC (flexible flat cable) connectors
  • DIP switches for easy stack up configuration
  • Supports Raspberry Pi A/B/B+ and Pi 2.
  • Supports Raspberry Pi V1 (OV5647) and V2 (IMX219) cameras
Pin Configuration:

DIP switches are used here for easy stack up configuration. When only one multi camera adapter board is used, the switches 1 and 5 should be switched to ON position. If two multi camera adapter boards are used, the downside board should be switched 1 and 5 to ON and upside board should be switched 2 and 6 to ON position, and if 3 or 4 multi camera adapter boards are used together each board layer should be configured as the Table 1 shown.

Table 1 – Pin Configuration

Operation:

For proper operation, only one camera should be enabled at a time. In the case where only one multi camera adapter board is used, driving Pin12 HIGH and driving Pin11 and Pin7 to LOW enables camera A on the adapter board. Please refer the Table 2 for camera selection configuration to enable cameras B, C and D. To disable all cameras on one adapter board, Enable 1 and Enable 2 signals should be toggled HIGH. Care should be taken that it is not allowed to drive the Enable 1 and Enable 2 LOW at the same time. When connecting more than two multi-camera adapter boards, only one of the cameras can be enabled by enabling the desired camera on one adapter board, and disabling all the cameras on the rest of adapter boards.

Software Demonstration:

Before using this product, the required “python-rpi.gpio” dependency must be installed with this command from the Terminal:

sudo apt-get install python-rpi.gpio

Then run the following Python code for a quick demo.

import RPi.GPIO as gp
import os

gp.setwarnings(False)
gp.setmode(gp.BOARD)

gp.setup(7, gp.OUT)
gp.setup(11, gp.OUT)
gp.setup(12, gp.OUT)

gp.setup(15, gp.OUT)
gp.setup(16, gp.OUT)
gp.setup(21, gp.OUT)
gp.setup(22, gp.OUT)

gp.output(11, True)
gp.output(12, True)
gp.output(15, True)
gp.output(16, True)
gp.output(21, True)
gp.output(22, True)

def main():
    gp.output(7, False)
    gp.output(11, False)
    gp.output(12, True)
    capture(1)

    gp.output(7, True)
    gp.output(11, False)
    gp.output(12, True)
    capture(2)

    gp.output(7, False)
    gp.output(11, True)
    gp.output(12, False)
    capture(3)

    gp.output(7, True)
    gp.output(11, True)
    gp.output(12, False)
    capture(4)

def capture(cam):
    cmd = "raspistill -o capture_%d.jpg" % cam
    os.system(cmd)

if __name__ == "__main__":
    main()

    gp.output(7, False)
    gp.output(11, False)
    gp.output(12, True)

Use the GPIOs according to the Table 1 and Table 2 configuration, to switch between different cameras to take photos or videos; use raspistill or raspivid commands to take photos or videos.
