TTGO Stick
Joystick Interface for TTGO ESP32
Hardware User Interface
If you have a TTGO ESP32 OLED 18650 Module, you might notices, that it comes only with two buttons. One for resetting the device and one to reprogram. But none to actually interact with the OLED Screen when holding it in your hand. Even though there is an ideal positioning of the thumb and index finger along the device. The Model you can find below, is the chassis for a thumbstick with a index-finger button. The WS28 Micro RGB Led Strips are optional. The print applies seamless to the device, gives it a nice grip control and makes navigating the OLED as ease of use. You can either use a thumbstick or a Joystick. For my Model I chooses the Sony PSP styled thumbstick to keep a narrow profile of the device. The 4pin Output is basically 2 analog ranges to measure and can easily be converted to on screen x and y coordinations to jump through menus or select options - for whatever needs you have. The printable parts make this device a very capable tool for all remote controlled cases where a display for details is necessary.
