Stepper Motor HAT (Compatible with Raspberry PI 2B/B+/A+) new VERSION V2

Product introduction

This expansion board is a fully functional robot extension on the market, which can support multi-channel Motor/ Stepper/Motor/Servo at the same time, and can be stacked with multiple boards to expand more control interfaces, especially suitable for DIY robots, smart cars, mechanical arms, intelligent head and other applications. The control interface is simple I2C interface, compatible with 3.3V/5V level, so it is also suitable for other development boards on the market.

Product features

1. Single power supply, normal working power supply voltage range is 5V~12V; (Please select the correct input voltage and current according to the controlled motor control voltage)

2. Complete data input/output through I2C bus of Raspberry PI.

3. One I2C interface, compatible with 5V level, can be connected to Arduino or other development board control

4. One I2C interface, can be connected to various sensors, expand a variety of applications

5. The address of the expansion module is determined by four address pins. Sixteen expansion modules are used simultaneously

6. Support 16-channel PWM output

7.12 bit resolution, adjustable PWM frequency up to 1.6KHz, configurable push pull or open drain output

8. Support 4-way steering gear interface, 3P standard interface, convenient to connect 5V steering gear and LED lights

9. Support two stepper motors of 6V~12V

10. Support four speed reduction motors of 6V~12V

11. Support infrared receiving function, convenient infrared control

 

Updated features for version V2

1. Improved 4-way steering gear interface, more convenient stacking use

2. Add 50Mhz crystal oscillator for PWM chip to provide better reference clock

3. Add I2C level conversion chip, support 5V level I2C sensor interface (default raspberry PI only supports 3.3V)
