Motor 2040 - quad motor controller 10V/0,5A - 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.

Motor 2040 - 4-channel motor controller 10 V / 0.5 A - RP2040 - Pimoroni PIM618.

• Based on the Raspberry Pi RP2040 microcontroller - ARM Cortex M0 + Dual Core 133 MHz with 264 KB of SRAM
• 2MB QSPI Flash with XiP support
• Two H-bridge drivers (DRV8833)
• 4 JST-SH 6-pin connector for connecting motors
• Wide range of motor and logic voltages supported (2.7V to 10V)
• Built-in voltage regulator 3.3 V with input voltage up to 13.2 V (the maximum current efficiency of the regulator is 150 mA)
• Measurement of voltage, current and error detection
• Current limit 0.5 A per motor
• Status LED for each engine
• Addressable LED / Neopixel
• Reset and Boot button
• USB Type-C connector for programming and power (max. 3 A)
• Qwiic / STEMMA QT connector for rapid prototyping
• Fully assembled

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.
