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
