Hub
The Hub is an interface device for 3rd party inputs. You can build your own input devices or connect compatible off the shelf products, like the Logitech Adaptive Gaming Kit.
Inputs
The Hub has 4 analog inputs (A1 to A4) and 6 digital inputs (D1 to D6).
| Abbreviation | Image | Hub inputs | Use cases |
|---|---|---|---|
| TRRS |  | A1/A2, A3/A4, D1/D5, D2/D6 | dual channel active devices, i.e joystick with 2 axes |
| TRS |  | All | dual channel passive inputs, i.e. 2 buttons |
| TS |  | D1 to D4 | single channel inputs, i.e. 1 button |
The 3.5 mm jack sockets have the following input assignments, see also Phone connector (audio).
| Input | T | R | R | S |
|---|---|---|---|---|
| A1 | A2 | A1 | A2 | 3.3V | GND |
| A3 | A4 | A3 | A4 | 3.3V | GND |
| D1 | D5 | D1 | D5 | n.c. | GND |
| D2 | D6 | D2 | D6 | n.c. | GND |
| D3 | D3 | n.c. | n.c. | GND |
| D4 | D4 | n.c. | n.c. | GND |
Settings
On Input 1 and 2, the Hub accepts stereo jack plugs with two analog signals. This is convenient for building Joysticks or other two-axis devices with just one cable. The second analog channel for Input 1 and 2 can be activated in the device settings.
