Description

The Grove Mouse Encoder is a precision electromechanical component designed to convert angular position or motion into a digital pulse train. It operates on the principle of mechanical contact switching, generating two square wave signals (Channel A and Channel B) with a 90-degree phase shift, enabling microcontrollers to determine both the direction of rotation and the relative speed.

Its integrated Grove connector eliminates complex wiring, offering a reliable interface for rapid prototyping and integration into control systems. The encoder’s durable mechanical design ensures stable performance in demanding applications, with a specified maximum rotational speed of less than 1000 radians per minute to maintain signal integrity and longevity.

Frequently Asked Questions

What is the operating voltage range for the Grove Mouse Encoder?

The Grove Mouse Encoder is designed to operate across a wide voltage range of 3.3V to 5.5V DC. This makes it directly compatible with both 3.3V logic platforms like Raspberry Pi and ESP32, as well as standard 5V Arduino boards without requiring level shifting.

How do I connect and read data from this encoder?

Connection is simplified via the standard 4-pin Grove interface. Connect the cable to any Grove Digital or I/O port on a compatible base shield (e.g., Arduino Grove Shield). The encoder outputs two digital signals (A and B channels) which must be read by a microcontroller using interrupt or polling routines to count pulses and determine direction based on the phase relationship between the two channels.

What is the resolution of this rotary encoder?

This mechanical encoder provides 12 pulses per single full 360-degree mechanical revolution. This translates to a resolution of 30 degrees per pulse. For higher precision, the quadrature output allows for counting both the rising and falling edges of both channels, potentially offering higher counts per revolution through firmware processing.

Is this encoder suitable for high-speed applications?

The encoder has a specified maximum rotational speed of less than 1000 radians per minute (approximately 159 RPM). It is best suited for low to moderate speed applications such as user interface dials, slow-moving actuators, or conveyor feedback. Exceeding this speed may lead to contact bounce, signal degradation, or mechanical wear.
