StereoPi v2 Standard

by HiPi

The world of stereoscopic video awaits! This board is the ultimate interface between two cameras and a Raspberry Pi Compute Module 4.

It comes with all the bells and whistles, including Ethernet, dual USB ports, GPIO header, microSD slot, HDMI output, and more. To use this board, you will need your own Raspberry Pi Compute Module 4, cameras, camera ribbon cables, and USB C cable.

StereoPi is an open-source stereoscopic camera based on Raspberry Pi. It can capture, save, livestream, and process real-time stereoscopic video and images. StereoPi opens up countless possibilities in robotics, AR/VR, computer vision, drone instrumentation, panoramic video, and more.

This kit includes:

  • StereoPi V2 Standard board
  • two short power cables (JST connectors) for advanced users
  • three jumpers

    StereoPi v2 key features:

    Friendly Powering Method

    You can now power the Stereo Pi v2 the same way as the Raspberry Pi 4! Just connect the USB-C power cable, and it works! Unlike the StereoPi V1 micro-USB connector, the USB-C connector on this new edition supports regular powering.

    Hot-swap reserved power!

    Both USB-C or JST connectors can be used to power up your StereoPi v2. You can swap them on the go without any work interruptions!

    Configurable power switch option

    To give you more flexibility with the enclosure design, two pins have been added on the board. You can now use an external switch that you can place anywhere to fit your design! No need to worry about the peak current your switch can handle! A new power management chip, able to commutate up to 4A current, will allow you to use tiny switches intended for an extremely low load!

    Hello, camera hackers!

    For advanced users, all I2C camera lines are on the board with 0 resistors gaps. This means you can use all the I2C you need for your special sensors. By physically connecting them to the appropriate GPIOs, you have hidden “dev board” features on the StereoPi V2. In addition to I2C, some other lines are pulled too.

    Say “hi” to the new Compute Module 4!

    More power!

    With the new SoC module from Broadcom, you have up to twice the speed in your OpenCV Computer Vision and DNN applications! And the fast DDR4 memory will add more speed to your memory-intensive applications (e.g. video capture and processing)

    WiFi onboard!

    Fast two-band Wi-Fi! No more USB dongle – you have a tested solution with brilliant drivers. Hey, drone makers! Did you know you can use an external antenna now? This is a big deal for your long-range FPV solutions (like WiFibroadcast, OpenHD, etc.)! Ah, and maybe WiFi boosters… You know what we mean, right? ☺

    Advanced wireless management

    Using the new CM4 wireless management features, you can physically power down your WiFi or Bluetooth through the software! Thanks to multifunctional GPIOs, introduced with the CM4, you can both power on/ off onboard wireless devices, and indicate their status by LED.

    Gigabit Ethernet!

    Thanks to the dedicated 1Gbit ethernet on the new Compute Module 4, there is no more compromise between the USB speed and Ethernet bandwidth!

    BLUETOOTH 5.0, BLE!

    All your project ideas for Bluetooth remote control can come true!

    Extremely fast eMMC!

    • flying through a forest,
    • flying through an unknown shaped/location static/dynamic gap,
    • accurate 3D pose detection of an independently moving object

    StereoPi is Easy to Use With Other Familiar Tools

    There are already many demos of StereoPi integrating with other tools, including:

    Example Video

    The video below was captured by running this simple command from a Raspbian terminal:

    raspivid -3d sbs -w 1280 -h 480 -o 1.h264
