Raven 4

• 400 Hz axial accelerometer, +/- 70 Gs
• 200 Hz lateral accelerometer, +/- 35 Gs
• 250 G single-axis accelerometer available as an option
• 20 Hz Baro data, +/- 0.3% accuracy!
• 20 Hz voltage on each of 4 deployment outputs
• 40 Hz output current
• 20 Hz high-precision temperature sensor
• 20 Hz for All flight events used for deployment logic.
• Flight counter
• All output program settings
• Accelerometer calibrations used during the flight
• Pad altitude ASL
• 8 minutes of high-rate data+ 45 minutes for each flight.  The newest 5 flights are stored.  (New faster download!)

4 high-current, programmable outputs:

• Two 30+ Amp outputs and two 9-Amp outputs compatible with batteries from a single Li-Poly cell to a 20V pack. 
• Default output settings:
  
  • Mach-immune, accelerometer-based apogee deployment
  • Main deployment at 700 feet
  • Baro-based backup apogee deployment
  • Backup deployment 1.5 seconds after main deployment
• Additional user-selectable output logic options can be selected in combination for each output:
  • Accel > user value 1 (ignition detection)
  • Accel < user value (burnout detection)
  • Filtered pressure increasing (baro apogee detection)
  • Filtered pressure decreasing (for staging)
  • Time > user value (simple timer)
  • Time < user value (vertical staging check)
  • Altitude < user value 1 (low altitude deploy)
  • Altitude > user value 2  (vertical staging check)
  • Altitude < user value 3 (landing detection) (New!)
  • Velocity < 0 mph (apogee detection)
  • Velocity < user value 1 (Mach inhibit)
  • Velocity > user value 2 (staging input)
  • Time delay after other conditions met (backup)
  See FIP page for programming screenshot
• All of the above flight events are recorded at 20 Hz in the Flight Event Register, great for verification of the altimeter functions in test flights or simulated flights.
• Screw terminal with 0.1" spacing

A sophisticated built in test exercises all sensors and all outputs with a realistic simulated flight.  Verify that your ematches work with your battery, verify your flight program, and view all the recorded data from your "flight" without leaving your computer.
