Common ground chain 2.8 and 4.8

This cable chain is designed to work with Samducksa (Crown) Joysticks or some generic Joysticks.

The Dupont connector included in this common ground chain, allows you to connect a defined number of buttons.

The distance between each button must be less than 15 cm (distance between each terminal).

The cable including the Dupont connector measures a distance of 35 cm.

You can connect either :

- 20 buttons, or
- 1 joystick and 16 buttons, or
- 2 joysticks and 12 buttons.

Please check the number of buttons and joysticks to be connected with the necessary lugs, to be sure to have enough. You can install several common ground chains with one installation. You will have to use 1 Dupont connector per chain, which will be connected to its own GPIO port (GRND).
