Thumbstick Trinkey - USB Key with miniature joystick

USB key form-factor board with a miniature analog thumbstick joystick.

USB-A plug
USB HID and power connection. Adafruit states the board plugs into any computer with a USB A jack and is pre-programmed as a small X-Y HID input.
Type · connector
X-Y analog thumbstick
Two-axis analog thumbstick used as the primary X-Y HID input.
Type · input
Button 1 tactile switch
One of the two tactile switches that Adafruit states acts as mouse button 1.
Type · input
Button 2 tactile switch
One of the two tactile switches that Adafruit states acts as mouse button 2.
Type · input
Rotation DIP switch
Dual DIP switch on the bottom used to set the rotation so that up is up.
