STM32F407IG motor development board

The hardware design of the Motor Development Board includes the following key features:

1. Rich Interface Support
As a dedicated motor development board, it provides extensive motor control interfaces for brushed DC motors, brushless DC motors, stepper motors, and servos, along with encoder interfaces and general-purpose I/O ports. Critical interfaces are optically isolated to enhance safety and reliability.

2. Flexible Design
The board's resources are highly configurable to adapt to diverse application requirements. It features 2 brushed/brushless DC motor driver interfaces, 4 stepper motor driver interfaces, and 3 servo interfaces. Through flexible configuration, multiple types of motors can be controlled simultaneously, with some interfaces supporting mixed motor types, greatly facilitating learning and development in motor control.

3. Abundant Resources
The main controller is an STM32F407IGT6 with 1024KB of Flash and 192KB of RAM, supplemented by an external 16MB Flash to meet demands for large memory and data storage. The board also includes interfaces such as RS232 serial, 100M Ethernet, CAN, and RS485, supporting a wide range of application needs.
