Pololu High-Power Motor Driver 24v23 CS
Supports 5 to 40 V voltage range
Delivers 23 A continuously without heat sink
Includes bidirectional current sensing
Enables motor coasting with extra input
Measures motor current up to 30 A
The Pololu High-Power Motor Driver 24v23 CS is a discrete MOSFET H-bridge motor driver designed for bidirectional control of high-power DC brushed motors. This compact board, measuring 1.8 by 1.2 inches, supports a voltage range from 5 to 40 volts and efficiently delivers a continuous current of 23 amperes without the need for a heat sink. It features an analog voltage output proportional to the motor current, enhancing its functionality.
This motor driver is equipped with an additional control input that allows for coasting, complementing the driving and braking capabilities of other Pololu high-power motor drivers. The board's performance is largely attributed to its N-channel MOSFETs, which have an absolute maximum voltage rating of 40 volts. However, to prevent damage, it is advisable to maintain a safe maximum voltage of approximately 34 volts due to potential ripple voltage on the supply line.
The driver is versatile, accommodating a wide range of currents and voltages, and can deliver up to 37 amperes of continuous current with an added heat sink. It offers a straightforward interface requiring minimal I/O lines and supports both sign-magnitude and locked-antiphase operation. Additionally, the board includes a current-sensing circuit capable of measuring bidirectional motor current up to 30 amperes, outputting an analog voltage.
Note: The board lacks reverse power protection and over-current or over-temperature protection, so it is recommended to use the integrated current sensor to prevent exceeding safe current levels.

If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product. (‘’RA’’) numbers are valid for 30 days, within which time the returned Products should be received by the Vendor. No returns will be accepted without having previously obtained an (‘’RA’’) number. The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
