Synchronized Stereo CAMERA HAT 1 Introduction Now Arducam released a stereo camera HAT for Raspberry Pi which allows you to connect two 5MP OV5647 or two 8MP IMX219 pi cameras to a single standard pi board, and takes images or video at the same time, even more important they are fully synchronized.
Synchronized Stereo CAMERA HAT 2 Features & Key Specifications Support all series Raspberry Pi boards, Pi HAT board style Two MIPI camera inputs and one MIPI camera output Support 1, 2 and 4 lane MIPI cameras input up-to 800Mbps/lane Support 2 lane MIPI output Support Raspistill (preview) and Raspivid (processing) commands for 5MP/8MP pi cameras with half resolution combine Support Arducam RPI cameras up to 16MP with proprietary camera driver with full resolution combine Support camera

Figure 4 5MP V1.3 Pi Camera Rework Instruction 4.2 Step 2 Attach the 22pin-15pin ribbon cable to the stereo camera HAT (22pin end) and Raspberry Pi CSI port (15pin end).
Synchronized Stereo CAMERA HAT 4.3 Step 3 Plug the stereo camera HAT on top of the Raspberry Pi, align the HAT Pin1 to RPI’s Pin1, then using the screws to fasten the HAT. Figure 6 Connect the HAT to RPi Board 4.4 Step 4 Attach the two camera 22pin ribbon cable to the stereo camera HAT. Figure 7 Connect two cameras 5 Quick Start Guide 5.1 Using Raspistill Command Run the following command from the terminal window to preview two camera feed at the same time.

Synchronized Stereo CAMERA HAT 6 7 GND Ground Power Ground ArduChip Registers ArduChip is the Arducam proprietary solution to control all the hardware internal logic to do the image capture and merge timing controls. There are set of register which allow users to switch to different mode according to their application. The stereo camera HAT acts like a standard I2C slave device, its registers are accessed from the Raspberry Pi Camera CSI port with I2C-0 bus and default 7-bit I2C slave address is 0x24.
