a) Qualcomm 8015
b) Qualcomm 20111
c) Qualcomm 234
d) Qualcomm 8013
Answer: a
Calrification: The Adafruit FONA 3G+GPS Breakout’s GPS capabilities is powered by the Qualcomm 8015 GPS Module. It enables geolocation services from the same device for all kinds of embedded and IOT applications. It can be controlled using the serial port.
3. What kind of commands does the Adafruit FONA 3G+GPS Breakout accept?
a) Analog Commands
b) BT Commands
c) AT Commands
d) TDM Commands
Answer: c
Calrification: The Adafruit FONA 3G+GPS Breakout accepts AT commands which can be provided from any computer that is connected to it. AT Commands are an abbreviation for Attention Commands which are generally used for manipulating different types of modems.
4. What will happen if we supply a voltage of 25V to the Vcc of the Adafruit FONA 3G+GPS Breakout?
a) Damage is caused
b) Module will shut down
c) Module will not respond for the time the voltage is applied
d) Module will function normally
Answer: a
Calrification: The Adafruit FONA 3G+GPS Breakout are mostly built to work on a voltage of approximately 5V. Any voltage lower than that and the board will not be able to power on, but however any voltage significantly above that and the board may suffer permanent damage.
5. Which port on any Arduino board should be connected to the Key Port on the Adafruit FONA 3G+GPS Breakout?
a) Any Digital Pin
b) Vcc
c) Gnd
d) Any Analog Pin
Answer: c
Calrification: The Adafruit FONA 3G+GPS Breakout’s Key pin should be always connected to the Gnd Pin on any Arduino Board. This pin provides the function of the power on/off indicator. When you would like to shutdown the board, connect the pin to the Gnd of the Arduino Board for about 3 to 5 seconds. However for prolonged use usage of the Adafruit FONA 3G+GPS Breakout one needs to permanently connect this pin to the Gnd of the Arduino.
6. What is the full form of the RI pin on the Adafruit FONA 3G+GPS Breakout?
a) Ring Indicator
b) Right Indicator
c) Right Impersonation
d) Rig Indicator
Answer: a
Calrification: The Adafruit FONA 3G+GPS Breakout has an RI pin which acts as a interrupt out pin for it. When a call is received on the module this pin becomes LOW, and is HIGH by default. Furthermore, it can also be used as an indicator for SMS.
7. How many LED indicators are present on the Adafruit FONA 3G+GPS Breakout?
a) 2
b) 1
c) 10
d) 4
