Description
Push Dip switches to the right (OFF position) to disconnect USB-to-
UART conversion chip from the XBee. This allows UART lines to be
individually selected to connect through the breakout connector or
the USB-C interface.
This connector attaches I2C-enabled devices to the development
board. Note that I2C needs to be available on the XBee in the board
for this functionality to be used.
Move both USB direct connect switches to the right (closed position)
and disconnect the USB micro port for correct operation of the I2C
to connector.
Pin 1: I2C_CLK/XBee DIO1
Pin2: I2C_SDA/XBee DIO11
Pin3: VCC
Pin4: GND
This part is a Texas Instruments HDC1080 temperature and
humidity sensor connected through I2C on XBee pins DIO1 and
DIO11. Move both USB direct connect switches to the right (closed
position) and disconnect the USB micro port for correct operation of
the I2C sensor.
This is the socket for the XBee (TH form factor).
Allows easy access to pins 1 to 20 of the XBee.
