Circular 30W BLDC Motor Driver PCBA

The Circular 30W BLDC Motor Driver PCBA is designed for compact brushless motor control applications where the drive electronics need to fit around the motor's mechanical structure. The board uses a circular FR-4 design with a large center opening and provides a 24V power input for a 30W motor system. Clearly marked U, V, and W positions show three-phase motor connections, and the onboard SDA and SCL signals provide an I2C communication interface for connection with an external controller. This layout fits compact fans, ventilation equipment, and other small motor-driven devices where PCB space and mechanical integration matter. The circuit holds motor control, power driving, signal communication, and supporting components on a compact ring-shaped PCB. Surface-mounted driver devices, control ICs, resistors, capacitors, diodes, and R100/R200 power resistors sit around the center opening. Electrolytic capacitors provide extra power filtering, and separate P1 and P2 connectors provide…
