What electronic components are needed for a joystick?

Autonomous GPS buoys come in two levels:

1. Standard buoy , controlled by a joystick (long-range LoRa protocol) for one to eight buoys, with local operation on the body of water

2. Advanced Buoy , controlled by a mobile phone application, but also by a joystick to fine-tune positioning visually on the water.

The joystick is similar for both standard and advanced buoys. The only difference is its communication protocol: LoRa in standard mode and ESP-Now in advanced mode.
