Overview:

  • Let your robotic dreams come true with the new DC+Stepper Motor HAT. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control, It also adds the capability to control 4 Servos with perfect timing.

  • Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.

  • In fact, you can even stack multiple Motor HATS, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.

  • Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capability, a big improvement over L293D drivers and there are built-in flyback diodes as well.We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested so all you have to do is solder on the included 2x20 plain header and the terminal blocks.

  • Stepper motors are great for (semi-)precise control, perfect for many robot and CNC projects. This HAT supports up to 2 stepper motors. The python library works identically for bi-polar and uni-polar motors.

  • Running a stepper is a little more intricate than running a DC motor but its still very easy

Features:

  • 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 5VDC to 12VDC.

  • Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)

  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.

  • Up to 4 Channel 12-bit PWM/Servo(5V)

  • One Infrared Receiver(GPIO26)

  • Big terminal block connectors to easily hook up wires (18-26AWG) and power

  • Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power

  • Works best with Raspberry Pi model A+, B+, Pi 2, or Pi 3;

  • Install the easy-to-use Python library, check out the examples and you're ready to go!

  • Pi HAT 2x20P Conector with Extra Long pin

Note

This board has a design flaw that requires multiple work-around solutions to make it operate with other boards because the PWM pins face upwards consuming space, per the manufacturer whom i contacted.

[information on how to set addressing for multiple HATs & Documentation]

  • 1. For the IR function, it is the same with this IR control board, please refer this WIKI page: raspberrypiwiki.com/index.php/Raspberry_Pi_IR_Control_Expansion_Board

  • 2. For other function, please refer to: raspberrypiwiki.com/index.php/Robot_Expansion_Board

  • 3. You may get some syntax error if you use the python 3 version for our sample code, It's just due to different versions of python. More detail refer to the above wiki URL;
