North Star Display Driver Board + Accessories

This display driver board is a direct clone of the one from Leap Motion’s original North Star design, and was engineered specifically to drive the two BOE VS035ZSM-NW0 displays.


The display driver IC is an Analogix ANX7530 controlled by an Atmel ATSAMD21G18 (the same MCU at the heart of the Arduino Zero) running Analogix and Adam Munich’s firmware. Firmware source, Altium design files, and Gerbers can be found in the Project North Star GitHub repository.


The board now comes with a Display Driver Debug Adapter and a USB Power Adapter Board (for supplemental power if necessary); and to deal with voltage drops that can occur when using long USB cable or powering a lot of things from one port, we’ve also added a power stabilizer that consists of a 470uF electrolytic capacitor and a 0.1F 5.5V ultracapacitor.


Note:

The ANX7530 on this board is not provisioned with an HDCP key, nor is it whitelisted with NVIDIA or AMD. That means that with any GPU driver released in at least the last couple of years, you won’t be able to use SteamVR Direct Mode with this board, no matter how many Vive Trackers or other sensors you add. Blame the movie, TV and recording studios, because they’re afraid that you might watch pirated copies of their content while in VR. HDCP is a DRM scheme about which you can read more here. Let’s just say that they absolutely will not issue keys for an open source design. Sorry to be the bearers of bad news but, at least for now, you’ll be running your North Star software in extended desktop mode.
