Product description: Motor 2040 - 4-channel motor controller 10 V / 0.5 A - RP2040 - Pimoroni PIM618
The Motor 2040 is a standalone motor controller designed to control DC motors with encoders. The module is based on the Raspberry Pi RP2040 , so there is no need to use additional boards with a microcontroller. Two DRV8833 drivers built into the board are able to handle four DC motors with a supply voltage from 2.7 V to 10 V and a current consumption of 0.5 A. The board also has an addressable RGB Neopixel LED, status LEDs for each engine, Boot and Reset buttons, and a Qwiic / STEMMA QT connector. The motor 2040 is powered via the USB type C connector.

Power Motor 2040
The Motor 2040 board can be powered via the USB type C connector from the computer or powerbank port or via the battery using the EXT PWR or VSYS pins. The module should only be powered from one source at a time. However, if the module is to be powered from two different sources at the same time, cut the jumper at the bottom of the board.
- Cut EXT PWR to VSYS if motors are to be powered separately (up to 10V) from the board. The power supply of the board (up to 13.2 V) will have to be provided via the USB 5 V or VSYS port.
- Cut the 5V USB to VSYS if the board is to be fully powered from a separate power source, without worrying about re-powering the computer. The board will not turn on when it is connected only via USB.

RP2040 microcontroller.RP2040 microcontroller
The RP2040 is the first microcontroller from the Raspberry Pi Foundation. This system was first used in the Raspberry Pi Pico module and in modules from other manufacturers, including Arduino. It is a very efficient, dual-core microcontroller based on ARM Cortex M0 + core clocked at 133 MHz . It has a large amount of built-in SRAM memory, programmable I / O (PIO) and other popular communication interfaces. The microcontroller is closed in the QFN-56 housing.
