Product introduction
This expansion board is a full-featured robot expansion version on the market that can support multiple motors/stepper motors/servos (Stepper/Motor/Servo) at the same time, and can be stacked to expand more control interfaces. It is especially suitable for various applications such as DIY robots, smart cars, robotic arms, smart pan/tilts, etc. The control interface simply adopts the I2C interface and is compatible with 3.3V/5V levels, so it is also suitable for other development boards on the market.
Features
1. Single power supply, the normal working power supply voltage range is 5V~12V; (Please select the correct input power supply voltage and current according to the motor control voltage you control)
2. Complete data input/output through the I2C bus for Raspberry Pi,
3. One I2C interface, compatible with 5V level, can be connected for Arduino or other development boards for control
4. One I2C interface can be connected to various sensors to expand various applications
5. The expansion board address is determined by 4 address pins, and 16 expansion boards can be used at the same time.
6.Support 16 PWM channel outputs
7.12-bit resolution, adjustable PWM frequency up to 1.6KHz, configurable push-pull or open-drain output
8. Supports 4-way servo interface, 3P standard interface, convenient for connecting 5V servo and LED lights
9. Supports 2-channel 6V~12V stepper motors
10. Supports 4-channel 6V~12V reduction motors
11. Support infrared receiving function for convenient infrared control
V2 version update function
1. Improved 4-way servo interface to make stacking easier
2. Add a 50Mhz crystal oscillator to the PWM chip to provide a better reference clock
3. Add an I2C level conversion chip to support 5V level I2C sensor interface (the default for Raspberry Pi only supports 3.3V)
Product interface description
