1. Power Supply and Basic Connections
Ensure the board receives appropriate power. The board itself can be powered via USB (5V) or TTL (3.3V). Servo motors require a separate power supply of 5-7.2V connected to the dedicated servo power input terminals.
2. Connecting to a Computer via USB
Connect the controller board to your computer using a standard USB cable. This connection is primarily used for programming and configuration. No additional drivers are typically required for basic functionality.
3. Connecting via TTL Serial Port
For communication with microcontrollers or other devices using TTL UART, connect the board's RX, TX, and GND pins to the corresponding pins on your device. Ensure voltage compatibility (3.3V for TTL).
4. Bluetooth Module Connection (Optional)
If using a Bluetooth module for wireless control, connect it directly to the designated Bluetooth interface on the board. Refer to the module's specific documentation for pairing and communication protocols.
5. Connecting to a Microcontroller
To integrate the servo driver board with a microcontroller (e.g., Arduino, Raspberry Pi, STM32), connect the microcontroller's VCC, TXD, RXD, and GND pins to the corresponding pins on the servo driver board. Ensure proper voltage levels and serial communication settings (baud rate 9600Kps).
작동 지침
1. State Control Method
The WitMotion servo driver board utilizes a state-based control method. Instead of calculating detailed servo movement parameters, you define specific 'states' for your servo motors. Each state can specify the position and speed for each of the 16 servos. The board then executes these predefined states sequentially or based on triggers.
2. Programming and Action Groups
The board supports up to 16 action groups and can store up to 8192 actions. This allows for complex sequences of movements to be programmed and stored directly on the board. You can define multiple states within each action group, specifying the duration (e.g., 1000ms) for each state.
3. 예ample Application: Badminton Shuttle Machine
The 16-channel servo motor driver can be used in various applications, such as controlling a badminton shuttle machine. In such a setup, the board controls the steering gears to move components up, down, forward, and backward, precisely positioning and launching badminton shuttles. This can be automated or controlled remotely via a mobile phone if a Bluetooth module is integrated.
