• Optical Finger Navigation OFN Module

The Optical Finger Navigation (OFN) Module can add a unique human interface component to your microntroller projects. OFN Modules are quickly becoming popular as user input devices in many smart phones as a replacement for trackballs, which are subject to mechanical wear and tear.

OFN technology is very similar to the technology used in optical mice, and movement across the sensor can be read by any microcontroller using I2C communication.

Features:

Built-in center select button

Onboard red LED which lights when finger movement is detected

Easy I2C communication interface with virtually any microcontroller

Onboard voltage regulator conditions I/O to 3 V max for compatibility with 3.3 V devices even when 5.5 V is supplied to Vdd

User-selectable 500 to 1000 counts per inch (cpi) resolution

User-definable 0 or 90° module orientation

Breadboard-friendly package with 0.1" pin spacing

Application Ideas:

Video game input

Mouse replacement

User input for computing devices

Key Specifications:

Power requirements: 3.3-5.5 VDC; 25 mA active, 1 mA standby

Communication: Two-Wire Serial I2C (400 kHz)

Dimensions: 1.0 x 1.0 x 0.55 in (25.4 x 25.4 x 13.97 mm)

Operating temp range: 32 to 158 °F (0 to 70 °C)
