ModalAI Electronic Speed Controller (ESC)

Still have questions? Check out the forum Here

ModalAI’s Electronic Speed Controllers (ESCs) are high-performing, closed-loop speed controllers that use a digital interface (UART, i2c in future).

Brief Overview

Brushless Electronic Speed Controllers (ESCs) are devices that consist of hardware and software for controlling three-phase brushless DC (BLDC) motors. ESCs communicate with the flight controller, which instructs the ESCs how fast the motor should spin.

ModalAI’s ESCs implement the following advanced features:

• Full integration with ModalAI VOXL and Flight Core PCBs
• Bi-directional UART communication with checksum; status and fault monitoring
• Real-time status and health reporting at high update rate (100Hz+ each)
• Closed-loop RPM control for best flight performance
• LED control from flight controller via UART
