Featuring NMOS H-Bridge design, it offers bidirectional control via PWM and DIR inputs compatible with a wide range of controllers. Integrated safety features include overcurrent limiting, temperature protection, and undervoltage shutdown, plus onboard test buttons and LEDs for quick diagnostics—ideal for robotics, automation, and high-power motor applications. ## Description The MD20A enables bidirectional control of one high-power brushed DC motor from 6V to 30V. With discrete NMOS H-Bridge design, this motor driver is able to support 20Amp continuously without any heatsink.The onboard test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way without hooking up the host controller.This motor driver can be controlled with PWM and DIR inputs. With input logic voltage range from 1.8V to 12V, it is compatible with wide variety of host controller (e.g. Arduino, Raspberry Pi, PLC).Features:Bidirectional control for one brushed DC motor.Operating Voltage: DC 6V to 30VMaximum Motor Current: 20A continuous, 60A peakButtons for quick testing.LEDs for motor output state.PWM and DIR inputs.Inputs compatible with 1.8V, 3.3V, 5V and 12V logic (Arduino, Raspberry Pi, PLC, etc).PWM frequency up to 20kHz (Output frequency is same as input frequency).Compatible with sign-magnitude and locked-antiphase PWM operation.Overcurrent protection with active current limiting.Temperature protection.Undervoltage shutdown.Example Application:Automated Guided Vehicle (AGV), Solar Tracker, Game Simulator, Mobile Robot, Automation Machine. ## Features - Support motor voltage ranges from 6V to 30V. - Bi-directional control for 1 brushed DC motor. - Maximum current up to 20A continuous and 60A peak. - Over current protection with active current limiting. - Temperature protection and undervoltage shutdown. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #137,859 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #100 in Motor Speed Controllers #801 in Tool Sets (Tools & Home Improvement) | | Customer Reviews | 4.9 out of 5 stars 23 Reviews | ## Product Details - **Brand:** Cytron Technologies - **Color:** Black - **Material:** Plastic - **Plant or Animal Product Type:** plant - **Recommended Uses For Product:** Automation, Robotics ## Images ![Cytron 20Amp Bi-Directional 6V-30V DC Motor Driver Speed Controller 60A Peak - Image 1](https://m.media-amazon.com/images/I/41etKcjIMYL.jpg) ## Questions & Answers **Q: Is there a library which contains the python code on how to communicate with this device?** A: For this product, we only have library for Arduino https://github.com/CytronTechnologies/CytronMotorDriver. However, we have made a tutorial for a similar motor driver (1Amp dual channel) using the phtyon code https://tutorial.cytron.io/2019/03/06/getting-started-with-maker-drive-and-raspberry-pi/. Please check if it helps. **Q: Why is there an asterisk for the direction? from the graph does it not say that if you set dir to high then it goes forward and low then it goes back** A: Forward or backward is just a representation. Actual direction is depending on the motor connection. i.e. reverse the motor's wire terminals at the board (MA & MB) will reverse the motor spinning direction. Thank you. **Q: I see that you have a arduino library, has it been tested or work with esp8266 or esp32?** A: Although we are not tested on esp8266 or esp32, but it is compatible. Just make sure the correct pin for PWM and DIR is selected **Q: Does this board have diodes (for reverse current) to take care of back emf from the dc motor?** A: The MOSFET already has the diodes built-in. This motor driver is a regenerative motor driver and the energy generated by the motor during deceleration will be pumped back to the power source. Make sure a rechargeable batteries is used to power the motor driver so that it can absorb this regenerative energy. ## Frequently Bought Together - Cytron 20Amp Bi-Directional 6V-30V DC Motor Driver Speed Controller 60A Peak - Nextion 5.0″ Intelligent HMI Display NX8048P050-011C-Y Capacitive LCD-TFT Touch Screen 800 * 480 with Enclosure, Support Video Audio Animation Play Functions. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/118008162-cytron-20amp-bi-directional-6v-30v-dc-motor-driver-speed](https://www.desertcart.sg/products/118008162-cytron-20amp-bi-directional-6v-30v-dc-motor-driver-speed) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-04*
