Note:
● Once connected, DF13 connectors are very reliable and are perfect for robotics and            
drone environments where vibrations are common. However, these connectors are         
not made for infinite plugging and unplugging. If you need to plug and unplug the              
sensorsfrequently,consideraddingamoresuitableconnectorinline.
● Please do not apply shear forces to the connector when pushing it in the socket.              
Ideally, press the socket down to the PCB with your thumb and push the connector in               
with your other hand. Do not use tools like pliers etc.! You can find good instruction               

1.5 UART Data Interface

The default interface is UART on pins 12 and 13. It needs an input voltage level of 5V (logic                  
high) to run reliably, the output voltage level is 5V. Please use a serial to USB interface (e.g.                 
such as the TeraRanger USB adapter) to connect the TeraRanger One to your PC. DO NOT               
connect the TeraRanger One to a real RS232 port of a PC, the voltage levels are different                
andmightdestroythesensor’selectronics.

The UART is configured to send and receive at 115200 bit/s, 8 data bits, no parity bit and                 
onestopbit(1152008N1).
1.6 TWI (I2C) Data Interface
Another way to connect to your TeraRanger One is the TWI (or better known as NXP’s I2C)                
interface. Using this interface, you can connect multiple TeraRanger Ones to a TWI master             
on the same bus. Please refer to the protocol description (chapter 5) to see how the bus                
address of each TeraRanger One can be changed individually to avoid collisions on the             
bus. Please keep in mind that the TeraRanger One has a relatively narrow field of view.               
Hence, multiple TeraRanger Ones looking into opposite or perpendicular directions can be           
triggeredatthesametime,allowingasignificantlyincreasedreadoutspeed!

Please refer to chapter 1.4 for the the electrical connections to be made for using TWI. The                
signal levels are 5V, the maximum bus speed is 400kHz and the pullup resistors (10kOhms)              
are already integrated in the TeraRanger One. If you want to connect to an I2C bus with                
