| "PS2 Thumb Joystick Game Controller Sensor Module w/ Cable for Arduino" |
| "Thumb Joystick is very similar to the 'analog' joystick on PS2 (PlayStation 2) controllers. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. The joystick also has a push button that could be used for special applications. When the module is in working mode, it will output two analog values, representing two directions. Compared to a normal joystick, its output values are restricted to a little smaller range (i.e. 10~1014). Only when the button is pressed, SW outputs low, otherwise it outputs high so that the MCU can detect the action of pressing.Features:- Operating voltage: 2~6V DC- Operating Current: 1mA (max)- Applications: Game rocker, smart car remote control, 4-axis aircraft remote controlGeneralBrandOPEN-SMARTModelN/AQuantity1 pieceForm ColorBlack + MulticolorMaterialPCB+Alloy+PlasticSpecificationApplicationApplications: Game rocker, smart car remote control, 4-axis aircraft remote controlWorking Voltage 2 - 6VDCVEnglish Manual / SpecYesDownload Link https://drive.google.com/folderview?id=0B6uNNXJ2z4CxLXFzQlZEcnFJalk&usp=sharingPacking List1 * Module1 * 5-pin cable (20cm)Package Weight:0.023kg (0.051lb)Package Size:5.4cm x 3.8cm x 4.5cm (1.97in x 1.18in x 1.57in)"
