Qwiic and I C
At the opposite side of the board. There are two pins labeled
SDA
and
SCL
which indicates the I C data lines.
Similarly, you can use either of the Qwiic connectors to provide power and utilize I C. The Qwiic ecosystem is
made for fast prototyping by removing the need for soldering. All you need to do is plug a Qwiic cable into the
Qwiic connector and voila!
The only I C address for this and all u-Blox GPS products is
0x42
, though each can have their address
changed through software.
Broken Out Pins
There are four other pins broken out: Pulse per second
PPS
, Reset
RST
, Safeboot
SAFE
, and finally the interrupt
pin
INT
. The first pin
PPS
outputs pulse trains syncronized with the GPS or UTC time grid. The signal defaults to
once per second but is configurable over a wide range. Read the
u-blox Receiver Protocol Specification
in the
Resources tab for more information. The reset pin resets the chip. The next pin,
SAFE
is used to start up the IC in
safe boot mode. The final pin
INT
can be used to wake the chip from power save mode.
