2 Joysticks. I currently use these to control pan and tilt on the camera assembly, and motor control.

An OLED  uOLED-128-G1 or uOLED-160-G1:

128 x 128 resolution, 256/65K true to life colours, PMOLED screen.

1.5" diagonal size, 45.5 x 33.5 x 6.3mm. Active Area: 27mm x 27mm.

 No backlighting with near 180° viewing angle.

Easy 5 pin interface to any host device: VCC, TX, RX, GND, RESET

Voltage supply from 3.6V to 6.0V, current @40mA nominal when using a 5.0V supply. Note: The module may need to be supplied with a voltage greater than 4.0 volts when using it with a SD memory card.

Serial RS-232 (0V to 3.3V) with auto-baud feature (300 to 256K baud). Rx line has built in series current limit resistor and a pull-up resistor.

Powered by the 4D Labs GOLDELOX processor (also available as separate OEM IC for volume users).

Rich set of built in graphics commands and functions.
