Number Item 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).
