Update: some people apparently just can't wait to get their hands on the mech source, so [http://bunniefoo.com/novena/novena-mech-rough.zip here it is] (110MiB), with the very strong disclaimer that it's disorganized, not final, and you'll need some expertise to even browse the files. Our aim is to clean this up into a nicely packaged form but for those who just can't wait this is what we can provide. Likewise, we offer no support on this interim CAD.
 
 
 
Also, if you're an experienced machinist you can skip this bit, but for people who think that things in mechanical CAD is as simple as dropping CAD into a 3D printer and stuff comes out that works, you are about to be sorely disappointed. Even in production, small tweaks happen relative to the CAD, and at prototype phase, the CAD is more of a guideline to the machinist than a strict design. We are working with a team of mechanical designers and machinists to roll all the DFM feedback into our source CAD, which we will share '''once it is done'''. However, this process takes a while. In other words, don't expect to be able to take the source link above and simply 3D print it and get a workable case.

Battery board

Battery management functions are implemented in an optional daughtercard.

Features:

  • SATA-style connector to route power and control signals to the main board
  • Works with battery packs used by most RC enthusiasts
    • 2S1P to 4S1P
    • Cheap and easy to buy
    • User can "pick their capacity" -- the battery life isn't fixed by design, it's up to the user
  • Classic Molex disk connector for battery connector
    • Requires adapter cable to the RC battery pack
  • Fast-charge capability
    • Rates in excess of 4A
    • Charge a 45Wh 3S1P pack in ~1 hour
    • Active cell balancing
  • Learns your battery pack
    • Over a few charge/discharge cycles, the controller determines the actual capacity of the pack
    • Tracks capacity degradation over time
    • Optimizes charging to reduce wear and tear on packs
    • Computes an accurate estimate of remaining battery capacity
  • Statistics reporting

  • STM32 master controller
    • Runs ChibiOS
    • Enables autonomous operation when CPU board is powered off
    • Reprogrammable by host CPU, but requires a physical button press to enable programming so as to prevent surreptitious malware insertion
    • Has DAC output to drive an analog panel meter

eDP Adapter

More photos: Novena PVT Hardware Photos

Novena natively supports a dual-channel LVDS interface for LCDs. However, today's LCD panels are migrating to an eDP-style interface. To bridge this gap, there is the eDP adapter board.

Features:

  • IT6251 chipset
  • DisplayPort 1.1a Tx supporting HBR (2.7Gbps) and RBR (1.62 Gbps)
  • Input pixel rate up to 165MHz
  • 24-bit color
  • Breakouts for touchscreen and USB
  • On-board switching regulators for low power operation
  • Made to work with Chimei Innolux N133HSE
    • 13.3" diagonal
    • 1920x1080, 166 ppi; 1.3W typ cell power, white pattern
    • IPS, 180 degree viewing angle in V/H
    • 350 cd/m2 brightness (3.5W typ backlight power @ max brightness)
    • 700:1 typical contrast ratio
    • 14ms Tr, 11ms Tf response times

Note to viewers: total power is cell power + backlight power. Cell power is just the power required to flip the LCD elements, not inclusive of backlight.

In addition, there is a custom flex cable that goes between the Novena mainboard and the eDP adapter. It's designed to handle the power requirements of the LCD, as well as manage signal integrity at high data rates.

Hardware Design Source

Please see Novena PVT Design Source for electronic CAD.

Please see Novena Mechanical CAD for mechanical CAD.

Firmware

Bootloader

u-boot is the current factory-default bootloader. Please see U-boot PVT Notes.

Linux OS

Kernel

Novena uses the stock Linux kernel with few patches. Any patches that might be useful to other projects (such as PCIe or ES8328 audio codec) are being submitted upstream.

The 2D/3D/Vector unit requires its own driver, which is available in source form on Github. Different userspace drivers require different kernel modules, so be sure to check out the branch that corresponds with your driver version.

The git repo for the cutting edge linux that we're working on is at:

https://github.com/xobs/novena-linux

Make sure you switch to the desired branch, e.g. 3.14-rc4 etc.

Those doing GPIO hacking with linux may be interested in the Definitive GPIO guide for the i.MX6.

Distro

Debian is the factory-default distribution, but of course anyone can put their favorite distro on the system.

Quickstart gide on building and initializing a bootable debian image:

For more in-depth discussions on Debian and other notes, please refer to these pages:

Dual Core Variant

Novena's base design works with the i.MX6DL. However, it does require some firmware changes. Notably, the bootloader is significantly different because there is much less SRAM to run from for setting things up. Also, the pinmuxes are different, so that issue has to be addressed in the device tree. See Novena/Dual Core for notes on this configuration.

Legacy

For those who want to cross-compile an OE-based image, please see building novena firmware

Software

Once you get Novena running, there are a few tweaks that you might have to make to the software to get it to run. Not all software likes running on Linux on anything other than x86/x64. Others just require software fixes to work around kernel bugs that we haven't fixed yet.

Please see Novena Software for more information.

Software projects

While Novena tries to be standard, it nevertheless has some platform-specific software projects that are necessary to take advantage of its unique hardware.

novena-eeprom: Command-line editor for the onboard EEPROM

novena-usb-hub: Manage the power status of each of the onboard USB hub's ports

Future software projects

novena-eeprom-gui: Graphical viewer/editor to inspect the onboard EEPROM

senoko-manager: Graphical manager for Senoko battery board

senoko-programmer: Firmware updater for Senoko battery board
