Pololu G2 High-Power Motor Driver 24v13
The Pololu G2 high-power motor driver is a discrete MOSFET H-bridge designed to drive large brushed DC motors. The H-bridge is made up of one N-channel MOSFET per leg; the rest of the board contains the circuitry to take user inputs and control the MOSFETs. The absolute maximum voltage for this motor driver is 40V, and higher voltages can permanently destroy the motor driver. Under normal operating conditions, ripple voltage on the supply line can raise the maximum voltage to more than the average or intended voltage, so a safe maximum voltage is approximately 34V.
The versatility of this driver makes it suitable for a large range of currents and voltages: it can deliver up to 13A of continuous current with a board size of only 1.3″ × 0.8″ and no required heat sink. The module offers a simple interface that requires as few as two I/O lines while still allowing for your choice of sign-magnitude or locked-antiphase operation. A current sense output gives an indicator of motor current, and the driver can limit the motor current to a configurable threshold. The power supply inputs feature reverse-voltage protection, while integrated detection of various fault conditions helps protect against other common causes of catastrophic failure; however, please note that the board does not include over-temperature protection.
The G2 High-Power Motor Driver24v13is a second-generation successor to our originalHigh-Power Motor Driver 24v12and can be used as a near drop-in replacement in typical applications. See “Differences from original high-power motor drivers” below for more details.
This version can be distinguished from the 18v17 by the number100on top of the tall silver electrolytic capacitor.
Features
G2 high-power motor driver versions
There are four versions of the single-channel G2 high-power motor drivers that share compatible pinouts, and eight versions of the dual-channel G2 high-power motor drivers. Four of the dual-channel drivers have the form factor of an Arduino shield, but they can also be used with other controllers as general-purpose motor drivers. The other four dual-channel drivers are in the form factor of a Raspberry Pi HAT and compatibleRaspberry Piboards (Model B+ or newer).
