accurac better than 200ns.

Trigger Input 20μs timing accuracy, Input levels. Low<0.5v, High>2.1v, biased to 2.5v
Latency4 CAN 30 or 150ms, pulse 12ms (INS)
Power Requirement:
Voltage 9 - 15V for SPEEDBOXBOX MINI
Power Consumption 2.7W 3W 4.7W
Weight5 500g
Dimensions5 160mm x 111mm x 27mm SPEEDBOX MINI
Antenna 3.3v, active

Notes:

  1. Either roll or pitch is available for the RTK option, not both simultaneously.
  2. A 6g factory option is available (resolution 2.94mg).
  3. This is the measurement resolution of the sensor, available internally to the SPEEDBOX MINI for calculations. Depending on the output message chosen, the full resolution may not be available in the output.
  4. Latency of the speed output, or all INS system outputs, compared to their timestamp, or when output using DAC.
  5. Weight and dimensions are for the base unit only excluding protruding connectors, and excluding any antennas. Please refer to the detailed drawings for further clarification.
