Mx1616 Motor Driver Datasheet File
11 Mar 2026 — The “dual” designation means a single L298N IC can independently control two DC motors or one bipolar stepper motor. Go to product viewer dialog for this item.

One evening after the festival, Jun sat on the lab floor amid reels of wire and a half-made control board. "Why Mx1616?" Jun asked.
Do not exceed these values, even momentarily, to avoid permanent damage.

Choose Mx1616 when you need a step up from A4988 in thermal performance but do not require the silent, high-resolution features of TMC drivers.
MOS technology results in an internal resistance of approximately 0.4Ω, reducing heat generation.
The L298N is large and inefficient, requiring large heat sinks. The MX1616 is smaller, cooler, and more efficient . | Register Address | Function | Bits |
