Data Sheet
3 Sensors
All sensors are connected to the I2C lines from header pins 3 and 5
(
see the header pinout
).

Board sensor details
4 Grove connectors
The Grove connectors provide easy access to the PWM
,
UART
,
and I2C pins from the baseboard
,
plus an on

board
analog
-
to
-
digital converter
(
ADC
),
as illustrated in
fi
gure 2
.
To interact with the AIN0 analog source
,
use address 0x49 on the I2C lines from header pins 3 and 5
(
see the header
pinout
).
