## Summary
BeagleBoard.org has announced the BeagleConnect QuadESC, a 60 x 48 mm PCB designed for controlling four brushless DC motors. It features an Arm Cortex-M33 processor with math and neural-network acceleration to manage three-phase power stages. The board provides extensive sensing capabilities, including current and voltage monitoring, and is supported by editable KiCad designs and open firmware.

## Technical specifications of QuadESC
- Uses a **200 MHz Arm Cortex-M33** processor with a trigonometric math unit and **TinyEngine** neural-network accelerator.
- Supports four three-phase power stages with dedicated PWM time bases.
- Includes **three-phase current sensing**, phase-voltage sensing, and board-temperature monitoring.
- Features onboard **CAN hardware** for system connectivity.
- Current sampling is handled by three analog-to-digital converters distributed across the four motors.
- Provided as **open hardware** with editable KiCad files and firmware sources.

## Why it matters
The project provides a hardware foundation for field-oriented control and AI-driven anomaly detection within the BeagleBoard ecosystem.
