Thumb Joystick Retail
Cost: $4.95 each
Description: This is a joystick very similar to the 'analog' joysticks on PlayStation 2 controllers. Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down. The joystick comes mounted on a breakout board and the pins are broken out to a 0.1" header and includes 4 mounting holes in the corners.
Note: You will need to solder the breakout board and the joystick together.
