MotoTwin

Dual 2A Motor Driver

---

Overview

A dual motor driver for two brushed DC motors at up to 1 A each between 4 and 18 V. Two screw terminal blocks keep the power supply separate from the DUELink bus. Set each motor's speed and direction independently with simple text commands over any supported interface.

Common uses: small two-wheel robots, classroom robotics kits, automated rolling toys, peristaltic pumps, and any project that needs two motors but doesn't need MotoMax's heavy current.

Key features • 4 to 18V • 2A (1A for each motor) • Screw terminal connections • External power terminal block • 37x37mm Overall Dimension

🌿 Cables not included

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.

Commands

Commands this module accepts. See Samples for runnable code in popular host languages.

Function	Description
SMotorA(s)	Sets Motor A s speed and direction (-100 to 100).
SMotorB(s)	Sets Motor B s speed and direction (-100 to 100).
DVer()	This driver version.

Peek under the hood

The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

MicroBlocks

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.

There are two ways to use it:

Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.

Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.

On-Module Code

Code that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.

Script

This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
