Description
1
Secondary USB
(USB MICRO B)
Secondary USB Connector for possible future use. Not used.
2
Current Measure
Large switch controls whether current measure mode is active or
inactive. When inactive, current can freely flow to the VCC pin of the
XBee. When active, the VCC pin of the XBee is disconnected from the
3.3 V line on the development board. This allows current
measurement to be conducted by attaching a current meter across
the jumper P10.
3
Battery
Connector
If desired, you can attach a battery to provide power to the
development board. The voltage can range from 2 V to 5 V. The
positive terminal is on the left.
4
USB-C Connector Connects to your computer. This is connected to a USB to UART
conversion chip that has the five UART lines passed to the XBee
device. The UART Dip Switch can be used to disconnect these UART
lines from the XBee.
5
LED indicator
Red: UART DOUT (modem sending serial/UART data to host)
Green: UART DIN (modem receiving serial/UART data from host)
White: ON/SLP/DIO9
Blue: Connection Status/DIO5
Yellow: RSSI/PWM0/DIO10
6
User Buttons
Comm DIO0 Button connects the Commissioning/DIO0 pin on the
XBee Connector through to a 10
Ω
resistor to GND when pressed.
RESET Button Connects to the RESET pin on the XBee Connector to
GND when pressed.
7
Breakout
Connector
This 40-pin connector can be used to connect to various XBee pins
as shown on the silkscreen on the bottom of the board.
8
UART Dip Switch
This dip switch allows the user to disconnect any of the primary
UART lines on the XBee from the USB to UART conversion chip. This
allows for testing on the primary UART lines without the USB to
UART conversion chip interfering. Push Dip switches to the right to
disconnect the USB to UART conversion chip from the XBee.
9
Grove Connector
This connector can be used to attach I2C enabled devices to the
development board. Note that I2C needs to be available on the XBee
in the board to use this functionality.
Pin 1: I2C_CLK/XBee DIO1
Pin2: I2C_SDA/XBee DIO11
Pin3: VCC
Pin4: GND
10
Temp/Humidity
Sensor
This as a Texas Instruments HDC1080 temperature and humidity
sensor. This part is accessible through I2C. Be sure that the XBee
that is inserted into the development board has I2C if access to this
sensor is desired.
11
XBee Socket
This is the socket for the XBee (Micro form factor).
