Description
DC Power Jack
I
The board can be supplied with power either from the DC power
jack (3.8V-5V), the USB connector (5V), or the VIN pin of the
board (3.8V-5V)
LED (PWR)
O
LED is lighted on when the board is power on from the MCU USB
port
LED1 (USER)
O
LED which can be controlled from MCU (D25). When the pin is
HIGH value, the LED is on, when the pin is LOW, it is off
LED2 (USER)
O
LED which can be controlled from MCU (D26). When the pin is
HIGH value, the LED is on, when the pin is LOW, it is off
LED (NET)
O
Indicate the BG96 operation status
LED (STAT)
O
Indicate the BG96 network activity status
MCU RESET
button
I
Reset the MCU
BG96 RESET
button
I
Reset the BG96 module
User Button
I
Connected to digital pin, D0, of MCU and can be used for user-
defined purposes
IOREF
O
Provides the voltage reference with which the MCU operates. A
device can read the IOREF pin voltage and select the appropriate
power source or enable voltage translators on the outputs for
working with the 5V or 3.3V
3.3V
O
3.3V generated by the on-board regulator. Maximum current
drawn is 300 mA. The regulator also provides power to the MCU
and BG96
5V
O
5V generated from the board. The board can be supplied with
power either from the DC power jack (3.3V - 5V), the USB
connector (5V), or the VIN pin of the board (3.3-5V). Supplying
voltage via the 5V or 3.3V pins bypasses the regulator and can
damage the board if it is not sufficiently regulated (This is not
recommended)
GND
Ground
VIN
I
Input voltage to the board when it uses an external power source (as
opposed to 5 volts from the USB connection or other regulated power
source). You can supply voltage through this pin, or if supplying
voltage via the power jack, access it through this pin
A0
IO
Six analog inputs which can provide up to 12 bits of resolution
(i.e. 4096 different values). By default, each input measures
from ground to 3.3 volts, though is it possible to change the
upper end of their range using the AREF pin
A0 can also be used as a DAC output and provides a 10 bit
voltage output with
Analog pins can be used as GPIOs

A5
IO
SCL
IO
I2C. The SCL (clock line). Can be used as GPIO
SDA
IO
I2C. The SDA (data line). Can be used as GPIO
