SwarmDrive: Development board for motor experiments based on ESP32

NickStick's SwarmDrive is a development board for learning and motor experiments. It is a mechatronics platform for users who want to learn and use small motors, especially brushless DC (BLDC) motors. The SwarmDrive development board contains a basic motor driver setup and an ESP32 microcontroller with Wi-Fi, Bluetooth, and USB connectivity.
With its ESP32 integrated board and rich teaching documentation, SwarmDrive allows professionals and students to easily learn various commutation algorithms and BLDC motor related knowledge. Users can download the console firmware and sample code to get started quickly. The open source code also has documents based on Espressif Systems ESP-IDF for users to refer to and learn. In this way, SwarmDrive serves as a starting point for users to gain insight into the inner workings of the drive motor algorithms.
The "Swarm" feature in SwarmDrive is inseparable from ESP32's excellent Wi-Fi and Bluetooth communication capabilities. Its powerful communication performance not only enables the development board/motor to communicate with multiple other development boards/motors to achieve the group characteristics of "Swarm"; it also enables remote control of the development board/motor.
