Kotleta 20 is an advanced sensorless BLDC propeller drive controller with CAN bus interface. It runs the Sapog* Firmware. Kotleta 20 has one CAN bus with two sockets onboard.
Excellent dynamic characteristics.
Regenerative braking and active freewheeling.
500 W continuous power output at 8.8 g weight.
Optional RPM control loop (RPM governor).
Self diagnostics and health status reporting.
Highly configurable.
Low noise and low current ripple due to the low-ESR embedded filtering capacitors and highfrequency PWM.
Supported interfaces:
CAN (ISO 11898-2)
RCPWM (analog PWM interface widely used in robotics).
High quality assurance:
Protection against unlicensed (counterfeit) production by means of a digital signature installed on every manufactured unit.
Open source firmware - Sapog (3-clause BSD license).
