Frontend
- Hardkernel Odroid XU-4
ARM-based Android computing frontend - Software to use network GPSd (TBD)
- Wired Ethernet link to backend
- Chalkboard Electronics 7" IPS TFT display w/ touch
- Blue Microphones Tiki
USB noise-canceling mic - DC switching power converter for Odroid
Backend
- Raspberry Pi 2
ARM-based Linux backend and network router - Nexus 5 Android smartphone
USB tethered to Pi for wireless data access - Async serial GPS module
Provides location data to GPSd on Pi - Febon100 UVC video capture
Provides MJPEG over USB video into Pi - 12V powered USB hub
Can feed 5V to Pi and additional power to N5
Management
- Freaduino Mega2560 (modified Arduino Mega clone)
System management controller - Resistors and analog ICs for voltage and current measurement
- Adafruit 2675 OLED display module
For system diagnostics and power monitoring - PowerStream 12V DC UPS module
I imagine the Arduino as something of a lights-out management controller for the entire system. The initial use is power monitoring and control. The Cosa software platform has been a wonderful help when developing for 'duino, as an event-driven approach is important to me. Check out my demo of voltage monitoring and text display.
