USB / PC connection for setup and upgrade
(USB and/or UART connection)
Ultra stable over temperature and time
Operational temperature: -30 °C to +85 °C
ST L3GD20 MEMS rate sensor
ARM Cortex-M3 processor for control and I/O
UART connection for system developers
Filters:
– Low pass
– High pass (programmable)
– Kalman (programmable)
– Rolling average (programmable)
Control algorithm:
– PID (proportional, integrative, differential)
– All gain parameters programmable (+3
Input Tx/Rx matching:
– Matching to any RC transmitter
– Allows a low cost system with high end
Curves (input stick curves):
– Many standard and also x4 use
– Good for aircraft control at low cost
Mixing functions / trim:
– Pitch into roll for “Wing” aircraft
– Power in and out (for curve transformation)
– Trim and range adjustments for fine tuning
3 PWM inputs and 6 outputs for control signals:
– Pitch
– Roll
– Yaw
1 x UART for 16-bit raw X, Y, Z rate and 8-bit
temperature digital data out and PC connection
