Gravity: DC Micro Metal Gear Motor with Driver (75:1)

The Gravity DC Micro Metal Gear Motor combines a compact drive motor, an integrated motor driver, and a 75:1 reduction gearbox in a single unit. It provides bidirectional speed control using standard signals, making it ideal for students, hobbyists, and makers building compact mobile robots.

Integrated motor driver

An onboard motor driver circuit eliminates the need for external H-bridge modules or dedicated motor shields. This reduces overall wiring complexity and saves space on compact chassis designs.

75:1 metal gearbox

The 75:1 metal gear reduction increases torque output while maintaining smooth rotational control. The durable metal construction handles mechanical load reliably during operation.

Bidirectional PWM and PPM control

The drive system supports both PWM and PPM control signals for flexible forward and reverse speed adjustment. This enables straightforward interfacing with microcontroller boards or standard radio control systems.

Gravity 3-pin interface

A standard 3-pin Gravity connection carries both power and control lines in a single plug. This allows fast, plug-and-play connection to compatible development boards and IO expansion shields.
