Motor 2040 - 4-channel DC motor controller with RP2040 microcontroller

Description

Module with a 4-channel DC motor driver based on the Raspberry Pi RP2040 microcontroller. RP2040 has two ARM Cortex M0 + cores operating at a frequency of 133 MHz and 264 KB of RAM. The microcontroller is not equipped with flash memory, but on the board there is an external memory with a capacity of 2 MB connected via the QSPI interface.

The board uses two DRV8833 systems (double H bridges), which allows you to control the movement of DC motors with a voltage from 2.7 to 10 V and a current of up to 0.5 A. The user also has inputs for connecting encoders, LEDs and buttons . The Qwiic / Stemma QT connector additionally enables the connection of modules with sensors and an I2C interface. The module can be used as a controller for building a four-wheel drive robot or a buggy.
