4I2C/UART backboard use
4.2I2C/UART interface
The TeraRanger Evo can be controlled through I2C or
UART interfaces. It 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.
The table below provides an overview of the pin out of the DF13 connector:
