I2C/UART Backboard Use
The TeraRanger Evo Swipe Plus sensor can output data through a UART interface using
an I2C/UART backboard.

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
DF13-2630SCF (tin) or DF13-2630SCFA (gold). Please consider the mechanical stability of
the mated connectors and avoid any kind of excess force on the connector (during
installation and once integrated) and follow the recommendations in the Hirose DF13
series datasheet (available here:
https://www.hirose.com/product/en/products/DF13
) to ensure a reliable connection.
