README
README.mdOpen Vision Computer (OVC)
Here is an outdated-but-maybe-interesting overview presentation of the project (March 2018).
This repo contains hardware, firmware, and software for an open-source embedded vision system: the Open Vision Computer (OVC). The goal is to connect state of the art open hardware with open firmware and software. There are a few revs:
- ovc0: three Python1300 imagers, an Artix-7 FPGA, DRAM, and USB3 via a Cypress FX3 controller.
- ovc1: two Python1300 imagers, a Jetson TX2 (6x ARMv8, GPU, etc.) connected to a Cyclone-V GT FPGA over PCIe.
- ovc2: two Python1300 imagers, a Jetson TX2 (6x ARMv8, GPU, etc.) connected to a Cyclone 10 GX FPGA over PCIe Gen 2.0 x4
- ovc3: three ON Semi AR0144CS imagers, USB Type-C peripheral, Trenz TE0820 module with Xilinx Zynq UltraScale+, RAM, flash, etc. Up to four optional external camera boards, each of which add a pair of AR0144CS imagers.
- ovc4: A Jetson Xavier NX carrier board with an NXP MCU, USB Type-C interface and six Picam compatible connectors.
- ovc5 (current work): based on Zynq UltraScale+ modules from Enclustra, with up to six external MIPI camera boards. Both Zynq USB SuperSpeed (5 Gbps) transceivers connect to an onboard USB-SS+ (10 Gbps) hub controller IC, which multiplexes them upstream via a USB type-C connector. Also has three Qwiic/STEMMA connectors and some random FPGA GPIO for low-speed expansion.
Where do I find stuff
Each camera family has its own directory in this repository that contains its relevant hardware, firmware, and software.
Hardware Design
We are using the very latest KiCAD: the nightly development builds. Installation instructions are here: https://www.kicad.org/download/ubuntu/
Once you have installed kicad-nightly on your machine, then you will
need to set up the repos as follows:
mkdir ~/hw
cd ~/hw
git clone ssh://git@github.com/osrf/osrf_hw
git clone ssh://git@github.com/osrf/ovcAdd the following line to your .bashrc file to set the KIWORKSPACE environment variable to point at your hardware folder:
export KIWORKSPACE=~/hwThen you should be able to view the latest developments:
cd ~/hw/ovc/ovc5/hardware/carrier

Questions
How big is the Mobof PCB?
It measures 110.5 × 50 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Mobof use?
225 parts, built around the TPS82130SIL, 74LVC1G34Z, SP3002-04JTG and TPS2069CDBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mobof KiCad files?
From the osrf/ovc repository on GitHub, at the commit this page was made from: the board is ovc2/hardware/ovc2a/graveyard/mobof/mobof.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mobof design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
