2. Multiple tablets Android/iOS mounted and powered
3. EMS Board compatible board
4. Camera install
5. Radio serial interface

Roadmap

1. Feedbacks: how many pilots can be interested to have a multi screen Glass Cockpit?
2. Define priorities on features based on "Easy Access" (USB Ready)
3. Prototyping Stratux with new sections easy to be integrated: Camera, HSI, ...
4. Find more compatible EMS boards
5. Integrate with existing EMS boards
6. Prototyping Stratux with new sections: EMS
7. Test flight and Review
8. Instrument Backup and recovery procedures
9. Radio interface

Techonlogies

EMS Compatible

• CAN based Rotax Engine 912is up to 916
• 912 ULS supported by https://avionicsduino.com/
• 912 ULS bridge to existing digital EMS

EMS Roadmap

Raspberry can easily support the following expasions with USB or HAT:

1. RS232
2. CAN
3. Bluetooth BLE
4. RS485
5. Linux socket for custom drivers

Cameras

• Any V4L Compatible cameras -----> Successfully tested, many cases requires motion to be installed
• WiFi Connected to Stratux network live streaming -----> Successfully tested
• MJPEG USB Camera -----> Successfully tested
• Composite Camera Input with USB Dongle -----> Successfully tested, many cases requires motion to be installed
  Not supported or not suggested Cameras:
• Other Cameras can be supported but CPU/Storage -----> Successfully tested, many cases requires motion to be installed

Autopilot

• RS232 Supported Autopilot with standard NMEA $GPRMB Course
• RS485 Custom protocol

Autopilot Sources

1. Map Point: live tap on the next waypoint
2. KML Import
3. GPX Import
4. iPad/Android running Navigation which can export data on WiFi (SkyDemon, EasyVFR, ....)
5. Integrate Search POI into the Stratux

Alarms

For safety reason the device Audio output shall be connected to a speaker, the system will play the following pre-recorded audio:

• GPS Speed Yellow arc during G meter >1.5G
• Sensor disconnection GPS or Traffic
• Traffic o'clock
• EMS Sensor Warning (Yellow)
• EMS Sensor Danger (Red)
• Fuel level
• Timer timeout
  The project reached 69 alarm conditions, filled by multi language audio samples:
• Italian

Backup Display

1. Minidisplay SPI
2. Display HDMI
3. EMS Source Companion

Radio Management

1. Connect the serial port USB->RS232 to the Radio and Enable the switch in settings, it will set the frequencies to the remote Radio
2. Whould you like to have a second RX Radio for COMMS? Adding a second SDR RTL Receiver with the Antenna set for AirBand
