About the QuadMotorHAT PCB
QuadMotorHAT is an open source PCB design by itsjeanxx12, published on GitHub under the MIT license. It is a 2-layer board measuring 65 × 56 mm, with 13 components from 9 distinct parts.
Other key parts include the L293D. By type, the board carries 5 capacitors, 4 connectors, 2 ICs, 1 diode and 1 resistor.
It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.
From the project
A custom Raspberry Pi HAT for controlling four DC motors with simple Python control.
A simple Raspberry Pi HAT for controlling four DC motors.
While making my WRO robot, I ran into a problem: I needed to control multiple motors from a Raspberry Pi without a mess of separate boards and wiring.
There are already plenty of motor HATs available, but I wanted something simple that fit what I needed. So I decided to design my own.
4 motor control — Control four motors from the Raspberry Pi using the included Python library. Screw terminals — Secure connections for the motors and power. Compact design — Keeps a low profile while leaving enough room for a cooling fan on the…
