Product Description

Important!  Currently, the huVVer-AVI devices require an external Dynon SkyView or Garmin G3X system to provide reliable air, system, and engine data. Future enhancement will use other data sources (both wired and wireless) to provide more flexibility.

Of note, MakerPlane and OnSpeed (www.flyonspeed.org) are both developing open source stand-alone precision ADAHRS systems that will be supported by the huVVer-AVI devices.  These will provide alternative flight data options for users to drive the screens.  These will be released later in 2021.

Overview:

The huVVer-AVI™ is a general-purpose customizable aircraft instrument that uses the Espressif Systems ESP-32 microprocessor. Instrument source code is provided for the popular Arduino platform, ensuring long-term support and enhancements from developers world-wide.  There are two versions of the instrument.  One is for a 2.25" instrument cutout and the other is for a 3.125" instrument cutout.  The only difference is the case the instrument is mounted in.  Be sure to select the correct version.  (The default selection is 3.125".)

Created for experimental aircraft applications, the huVVer-AVI provides a bright 2.4 inch (61 mm) LCD screen, dual RS-232 serial ports, a CAN bus interface, two relay or lamp drivers, two sensor inputs, a pair of stereo audio outputs, and four front-panel pushbuttons that fits into a standard aircraft 2.25” or 3.125” panel cutout. Operating at input voltages from 8 to 35 volts, and withstanding voltage surges of up to +/- 100 volts, the device is ideally suited to aeronautical applications.

Arduino (www.arduino.cc) is an open-source hardware/software integrated development environment (IDE), originally created as an educational tool. It has been widely adopted by small to medium sized companies as the platform of choice for quick-turn development of custom microcontroller applications. Developers worldwide support the millions of Arduino users, providing readily available, low cost hardware and open-source software.

The huVVer-AVI family was developed to be production-ready prototyping systems. Fully compatible with the Arduino or Espressif IDE development environments, it provides robust power conditioning and multiple levels of protection from electrostatic discharge, over voltages, and short circuits. The devicesvfit into standard aviation 2-inch or 3-inch circular instrument cutouts.

  • I/O capability
    • Two general purpose (0-5 volt) sensor inputs.
    • Left and Right stereo audio (8-bit) for alarms and signaling. 300 ohm source impedance.
    • Two 50 Volt open-collector I/O channels for driving external lamps or relays, with on-board coil suppression.
    • Two RS-232 Serial ports.
    • One CAN based Two-Wire Automotive Interface (TWAI, compatible with ISO11898-1)
    • One Universal Serial Port (USB) for program development.
    • 5 Volt power output for powering external sensors.

  • The initial flight instrument library includes the following
    • Airspeed Indicator,
    • Altimeter,
    • Heading Indicator,
    • Attitude Indicator,
    • AOA indicator, and
    • Various debug pages (to assist in installation and program development).

  • Most instruments are configurable to display supplementary information, to change units, or to configure ranges and thresholds.

Installation:

For installation, you will need Mil-spec wire, a number of crimp terminals and at least one connector housing. Appropriate terminal crimper, wire cutter and wire stripper tools are also required.

Crimp Pins: Digikey WM2312-ND. Note: MakerPlane supplies 10 pins with each instrument.


Connector Housing: DigiKey WM2006-ND. Note: MakerPlane supplies two housings with each instrument.


Wire and wiring supplies: Mil-spec M22759/16-22 (22 AWG single), M27500/20SB1T23 (22 AWG shielded single wire), M27500/22SB2T23 (22 AWG shielded pair), plus a circuit breaker as required.

Available from Aircraft Spruce or ProWire USA.
