Motor control board for raspberry pi

Types of Motor Control Boards for Raspberry Pi

Motor control boards for Raspberry Pi handle the tasks of reading signals from a controlling device, amplifying the signals, and finally sending the amplified signals to motors. There is a wide variety of these motor control boards and each is different regarding motor type, control mechanism, and operational use.

These boards are important for system modularity. That means one control board can be designed to control several motor types and one motor can be designed to work and be controlled by various control boards. This flexibility allows for the simplified and complicated design of systems. The following are the types of motor control boards for a Raspberry Pi:

HAT Motor Driver Boards

HAT Motor driver boards are designed or can be used with Raspberry Pis that support the HAT feature. These motor control boards have small, standard, and removable parts. HATs have a small number of sockets that can be pin compatible and attached to the same Raspberry Pi models. They also have standardized connectors.

The HAT feature has an EEPROM that stores information about the HAT's pin and power options. This means a HAT board can be plugged into a Raspberry Pi and the Pi can read the HAT information for easy usage. These motor driver boards are great for robotic and mobile applications because they are small and powerful.

Accessory Boards

There are many HATs that require features without the addition of a connector, so these went into the field of accessory PCBs. Similar to the HATs, Accessories PCBs are boards that help add some features to a Raspberry Pi but without the added connector. Instead, these boards, like the motor control board for Raspberry Pi, are designed so one could solder them onto a Raspberry Pi.

However, although they lack connectors, they offer more features than HATs. These boards have additional sensors, cameras, and modules and are used in more complicated projects. Accessory PCBs are more flexible, as they can be customized according to projects, while HATs are more standardized and easier for simple projects.

Augmented Boards

There are also some Extension PCBs that add features without the additional connectors. Augmented Motor Control Board for Raspberry Pi is similar to HATs, but unlike HATs, which require soldering, these boards have external male connectors designed to connect to Raspberry Pi GPIO connectors.
