3 1 Introduction ArduCAM Nano RPI module is 24x24mm coin size Raspberry Pi compute module which is designed for the applications where the size and weight is a matter. The board is based on Broadcom BCM2835 processor which has 600MHz ARM1176JZ-K and VideoCore IV GPU inside. The Nano RPI has rich peripherals including two CSI camera interface, PAL video output, SPI, I2C, UART, GPIO and etc. Together with its mother board, it can be a quick prototype dual camera system. 2 Application stereo camera Robot controller UAV controller smart watch Other battery-powered products 3 Features Figure 1 ArduCAM Nano Raspberry Pi Compute Module Processor: 600Mhz BCM2835 ARM1176JZ-K with VideoCore IV Memory: 512MByte DDR2 Dual CSI-2 interface SDTV: PAL output Peripherals: USB,SPI, I2C, UART, GPIO Power input: micro-usb or Battery Small form of factor, mother board is 36x36mm 4 Key Specifications Power supply microusb :5V Battery: 3.7V Nano RPI Size: 24 x 24 mm Mother board size: 36 x 36mm CPU speed: 600MHz Memory : 512MB DDR2 30fps 1080p H.264 video encode/decode Temperature: -25 ~+85 Weight: 10g 2

4 5 Pin Definition The mother board pin out is derived from the nano RPI module's pin out. See the Table 1 and Table 2 for the detail pin out of Nano RPI module and its mother board.

6 6 Operation System The Nano RPI module use the same operation system Raspbain like the standard Raspberry pi boards. User can download the OS from the link: 7 Quick Start Guide 7.1 Hardware Reqirement User need to prepare the following items to run the Nano RPI module. LCD screen with AV input AV adapter cable Micro-USB power cable Micro-USB to USB type A adapter cable USB-hub for keyboard/mice 7.2 Start the Raspbian System Plug in the AV cable to the AV output connector. Insert the preinstall the Raspbian operation system into the TF-card socket, then power up the board with micro-usb power supply. After few seconds, the boot information will be displayed on the LCD screen, and the Raspbian will enter into the desktop after successfully boot. 7.3 Enable Standard Dual Camera Support First copy the provided dt-blob.bin into the /boot partition then plug in two standard pi camera boards into the CSI-2 camera interface and reboot the system. Using the follow command to determine if the system support the dual camera. sudo vcgencmd get_camera There should be support camera = 2, detected camera = Enable Share Oscillator Stereo Camera The following step needed for shared oscillator stereo camera, because both of the camera should be powered before running the stereo camera command. Run the following command to generate new dtb file. Then reboot the OS. Copy this dt-blob.bin to /boot partition then reboot. 5

7 dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-dualcam-sync.dts Now that the camera GPIOs are released the control from GPU, it is the responsibility of user to take care of these signals. Raspi-gpio is a good tool to control the GPIOs from the command line, using the following command to install the package. sudo apt-get install raspi-gpio Using the command below to figure out how to use the raspi-gpio command, and the meaning of the parameters. raspi-gpio help Before running the cameras, the following commands should be ran first each time after reboot. raspi-gpio set 2 op pn dh raspi-gpio set 3 op pn dh raspi-gpio set 30 op pn dh raspi-gpio set 31 op pn dh Normal read operation reads each image data by sending a read command in one SPI read operation cycle. While burst read operation only need to send a read command then read multiple image data in one SPI read operation cycle. It is recommended to use burst read operation to get better throughput performance. 7.5 Run the Stereo Camera Now you can run the stereo camera with the following command. raspivid -w h 480-3d sbs -o stereo.264 The captured stereo.264 video file will look like this, side by side view. 7.6 Install Gstreamer Update software source sudo apt-get update Install the Gstreamer sudo apt-get install gstreamer1.0-tools Install the GStreamer extension component. 6

Using Notepad to edit the file will make it hard to tell where the line breaks are, and this file uses line breaks to separate the commands. Scroll down to the bottom of the file and add dtoverlay=dwc2 to a new line: 8

10 Save and exit the config.txt file. Now open the cmdline.txt file with Notepad. Make sure Word Wrap is off to view the file as a single line. You don t want to add any line breaks to this file. All of the commands need to be in a single line. If you use Wordpad to edit this file, you may create unintentional line breaks, so using Notepad is best. Scroll across the line and find the command rootwait. After the rootwait command, add modules-load=dwc2,g_ether: Save and exit the cmdline.txt file. Insert your SD card into the Pi Zero, and plug your micro USB to USB adapter (or cable) into the Pi s micro USB port (not the power connection), and the other end into your computer: 9

11 You ll see that Windows recognizes the Pi, and will attempt to setup the device: At this point, open PuTTY and try SSHing into the Pi with the address raspberrypi.local: 10

12 If you can log in to your Pi at this point, that s good. You can skip the next section, Install the RNDIS Drivers and go to the Setting Up Shared Internet Access further below. If you do get an error message saying something like Unable to open connection to raspberrypi.local. Host does not exist, you ll just need to install the RNDIS drivers on your computer. I ll explain how to do this in the next section: INSTALL THE RNDIS DRIVERS With your Pi Zero still connect to your computer, navigate to the Windows Device Manager. Under Other devices find RNDIS/Ethernet Gadget, and right click on it. Then click Update driver software from the menu: 11

13 Now click Let me pick from a list of device drivers on my computer : 12

14 Scroll down the list and select Network adapters, then click Next: Now scroll down the Manufacturers list in the window on the left, and select Microsoft. Then scroll down the Network Adapters list on the right side window until you find a line that says Remote NDIS Compatible Device. Select that, then click Next: 13

15 A warning will pop up about Windows not being able to verify the driver, but just click Yes to get past it: After the driver is finished installing, you should see something like this: 14

16 Now try to log into your Pi with PuTTY using the address raspberrypi.local. You should be able to get in: 15
