Wiring

The UGT RaceLCD has been designed to be as easy as possible to wire up.  Solder cables to the correct solder points and connect them to the inputs for your wheel.

Please note that Analogs 4-8 can also be used for Rotary Switches.
The back of the Race LCD has the following solder pads:
24 buttons
8 Analogs (1-8 pots or 1-4 pots and 1-4 rotary switches)
6 Encoders
1 Hat Switch
1 USB
6 Extra LED’s
Buttons

The first terminal for each button is wired to GND (shown in black).  A wire can be run from GND to the first button and continued to the next and the next etc.  The same wire can be used to connect all buttons
 
Please note, button 30 is used as an emergency boot loader.  If you hold this button down while the device is booting the device goes into firmware update mode.  It is not advisable to wire a latching switch into this input. 
 
 
Potentiometers
 

One side of each pot is wired to GND (shown in black).  A wire can be run from GND to the first pot and continued to the next and the next etc.  The same wire can be used to connect all pots.  

The other side of the pot is wired to 3.3v (shown in red).  The same wire can be used to connect all pots.

The center of the pot is wired to the analog pad (shown in blue) 

All 8 analogs can be used to connect 8 pots, however, it is also possible to wire in rotary switches to analogs 5-8 – you cannot wire rotary switches into analogs 1-4. 

Rotary Encoders

 

The center of the rotary encoder is wired to GND (shown in black).  A wire can be run from GND to the first pot and continued to the next and the next etc.  The same wire can be used to connect all pots.  
 
For the first rotary encoder, one side of the rotary encoder is wired to 1a (shown in blue).  The other side of the rotary encoder is wired to 1b. Wire the second rotary encoder into 2a/2b 3rd into 3a/3b etc. 
 
Please check your rotary encoder instructions to make sure you wire it in the correct way round. 
 
Do not confuse rotary encoders and rotary switches.  Rotary encoders are digital and are not the same as rotary switches which are analog.
