Product Description
This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 36 V operating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The default pin mappings make it easy to get started, but they can be customized for more specialized applications. This version ships fully assembled with connectors soldered in.
- PWM operation up to 100 kHz
- Motor indicator LEDs show what the outputs are doing even when no motor is connected
- Integrated 5 V, 2.5 A switching step-down voltage regulator powers the Raspberry Pi base for single-supply operation
- Python library makes it easy to get started using this board as a motor driver expansion board
- GPIO pin mappings can be customized if the default mappings are not convenient
- Current sensing and limiting pins are exposed for advanced use
- Reverse-voltage protection
- Undervoltage shutdown
- Short circuit protection
- Operating voltage: 6.5 V to 36 V (absolute maximum; not intended for use with 36 V batteries)
- Maximum can be increased to 40 V if regulator is disconnected (see below)
- Output current: 14 A continuous
- Active current limiting (chopping) with approximate default threshold of 40 A (can be adjusted lower)
This version of the 24v14 motor driver is fully assembled, with a 2×20-pin 0.1″ female header (for the Raspberry Pi interface) and a six-pin strip of 5 mm terminal blocks (for board power and motor outputs) soldered in. It can be distinguished from the other versions by its red PCB and the number 100 on top of the six tall silver electrolytic capacitors at the corner of the board. (See item #3752 for a kit version with connectors included but not soldered in.)
Dimensions
- Size: 65 mm × 56 mm
- Weight: 30 g. Without included mounting hardware.
General specifications
- Motor channels:2
- Minimum operating voltage:6.5 V
- Maximum operating voltage:36 V. Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 30 V, which leaves a safety margin for ripple voltage on the supply line. Disconnecting on-board regulator increases absolute maximum to 40 V. Not recommended for use with 36 V batteries.
- Continuous output current per channel:14 A. Typical results at room temperature with both channels running at 90% duty cycle.
- Maximum PWM frequency:100 kHz
- Reverse voltage protection?:Y
- Partial kit?:Y
