Gimbal Joystick with Adapter (#27808)

Gimbal Joystick with Adapter (#27808) 

This quad-bearing gimbal joystick provides a two-axis resistive output for controlling position, velocity, 

tilt, etc., as an input device to various microcontrollers, including Parallax’s P8X32A Propeller chip and 

BASIC Stamp family of modules. It may be used with microcontrollers that have analog inputs, with an 

external ADC, or with resistor-capacitor circuits for a purely digital solution.  

 

The Joystick comes pre-wired with a 6-wire cable and 1.5 mm plug. An adapter kit with a matching 1.5 

mm socket is included, for convenient prototyping on breadboards or thru-hole boards. Simple soldering 

is required to use the optional but highly recommended adapter. 

Features

 

 

kΩ

 linear-taper potentiometer on each axis 

 

Smooth ball-bearing action on both axes  

 

Selectable spring return-to-center on 

vertical axis 

 

Selectable detents and/or friction on 

vertical axis 

 

Adapter kit for 0.1” spacing is included for easy 

prototyping (simple soldering required) 

Specifications 

 

Power Requirements:  Passive device; will 

work with any low-voltage supply 

 

Interface: Resistive or voltage divider output 

 

Dimensions:  2.70 x 2.32 x 2.42 in 

(68.6 x 58.9 x 61.5  mm) 

Application Ideas 

 

Game controller 

 

Remote control for robotics 

 

Manual control for interactive displays
