I2C/UART Backboard Use

 

The TeraRanger Evo People Counter sensor can output data through a UART interface

 

 

 

 

 

 

 

 

 

   

 

 

using an I2C/UART backboard. 

 

Figure 8 - I2C/UART backboard front view 

4.1.

I2C/UART pinout 

 

 

The I2C/UART backboard uses a single 9 pin Hirose DF13 connector for interfacing to

 

 

 

   

   

 

 

 

 

 

   

the host system. The mating connector is a Hirose DF13-9S-1.25C with crimping contacts
