Holybro Kotleta20 CAN bus BLDC Smart ESC for Pixhawk / PX4 - 1PC

Kotleta 20 is an advanced Can bus controller of sensorless BLDC motors designed for autonomous applications running UAVcan protocol such as pixhawk and PX4 systems.

The Kotleta 20 ESC runs Sapog – an open source multiplatform BLDC controller firmware developed by Zubax Robotics.

UAVCAN ESCs have a number of advantages over traditional PWM ESCs:

• UAVCAN has been specifically designed to deliver robust and reliable connectivity over relatively large distances. It enables safe use of ESCs on bigger vehicles and communication redundancy.
• The bus is bi-directional, enabling health monitoring and diagnostics.
• Wiring is less complicated as you can have a single bus for connecting all your ESCs and other UAVCAN peripherals.
• Setup is easier as you configure ESC numbering by manually spinning each motor.

Simplified wiring - ESC Can Bus connections are wired into each other as a daisy chain and their order doesn't matter. A single connection is then made with the FC.

A power input is required to each ESC.

Features

• 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 high frequency PWM.
• Supported interfaces:
  • CAN (ISO 11898-2)
  • UART.
  • 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).
