Description

Shield with dual-channel driver pf motors operating with voltages from 6.5 V up to 30 V and current up to 22 A per channel (max 60 A). The system can be connected directly with GPIO connectors of minicomputer Raspberry Pi GPIO 3, 2, B+ and A+. The rotation speed can be controlled by the signalPWM.

 

The kit includes: module, screw connection, goldpin strip, screws and spacers for the self-installation.

In combination withthe Raspberry Pi, when using a specially preparedlibrary you can easily control the speed and direction of rotation of two DC motors. Form and pins of the board to allow direct connection to minicomputer. The system uses a 40-pin GPIO connector.

The subject of sale is the shield with the driver of motors, minicomputerRaspberry Pican be purchased separately.

The product is compatible with Raspberry Pi

The manufacturer provides alibrary of Python for users of the Raspberry Pi.

Modes of operation

The power supply of the motors was separated fromthe Raspberry Pi. Voltage from a range of 6.5 V to 30 V should be connected to pins VIN and GND. Power supply of the logic part 3.3 V is consumed from minicomputer.

Connection

The following table shows which pins of the Raspberry Pi are used by driver of motors:

 

Pin RPi

GPIO

Pin of a

driver

Description
5 Motor 1 FLT

Status pin. By default, in the high state. When an error of driver is detected, the driver switches to a low state.

6 Motor 2 FLT

Status pin. By default, in the high state. When an error of driver is detected, the driver switches to a low state.

12 Motor 1 PWM

The PWM inputs to control the rotation speed of the motor.

The maximum PWM frequency is 100 kHz.

13 Motor 2 PWM

The PWM inputs to control the rotation speed of the motor.

The maximum PWM frequency is 100 kHz.

22 Motor 1 SLP

By default, in the low state, it indicates the disabled outputs of the motors. To run the driver, you must specify the high status.

23 Motor 2 SLP By default, in the low state, it indicates the disabled outputs of the motors. To run the driver, you must specify the high status.
24 Motor 1 DIR

Pin to choose the direction of rotation. In the low state, the current flows from output A to B. In high state - from B to A.

25 Motor 2 DIR Pin to choose the direction of rotation. In the low state, the current flows from output A to B. In high state - from B to A.

 

Modes of operation

The table shows the operation modes depending on the inputs:

 

SLP DIR PWM MxA MxB Mode of operation
1 0 PWM PWM (H/L) L Forward rotation at a certain speed PWM %.
1 1 PWM L PWM (H/L) Back rotation at a certain speed PWM %.
1 x 0 L

L

Braking (outputs connected to ground).
0 x x Z Z Disabled output.
