Learning about serial communication concept and history. Simple to understand examples and experiment for UART, RS232, Ethernet, Wifi, USB, SPI, I2C. Ublox NEO6. MV2 Neo 6. M GPS Module with Arduino. Ublox Neo 6. M Ublox NEO6. MV2 is a I2. C compliant GPS module. This post discusses details on wiring Ublox Neo 6. M with Arduno or an USB to SerialTTL adapter, basic interactions with module using serial communication, using u center GUI in visualizations, as well as using Tiny. You will need a rs232 serial cable. If your pc or laptop doesnt have the port you can purchase a usb to serial cable. Once you have that and can. Think you have what it takes to join the IoT.

USB to Serial converter HL340 download 32 and 64 bit windows drivers PIDVID 43485523 Due to some reasons I had to run Windows XP on Virtualbox. GPS library to extract fine grained results from the module output. Please note that most of the points except for Tiny. GPS library based sample can be checked only with USB to SerialTTL adapters. Hence, all other steps can be followed even without an Arduino. Wiring. I recently purchased a Neo 6. M board labeled GY GPS6. MV2 and according to descriptions of board, input voltage range was 3. V 6. V Caution Be careful and check if input voltage of 5. V can be directly applied with the board module being used. But IO maximum logic level is rated at 3. V which might be a problem while connecting the device with Arduino which works with 5. V logic level. After going through ATmega. V should be just enough for Arduino to pick up. Therefore, TX pin of NEO 6. M can be directly connected with Arduino Sparkfun has a nice article on serial communication. However, it is problematic if NEO 6. M would be able to handle 5. V logic signals coming from Arduino. Even though, some sources confirm that directly connecting module with Arduino does not do any harm, it is not clear if there really is any side effect in long run. Note Same applies to USB to SerialTTL adapters. Perfect method to overcome all these logic level problems is to use a Bi Directional Logic Level Converter. Advantage of Bi Directional Logic Level Converter is that in can step down voltage in one direction while being able to step up the voltage in the reverse direction. For an example, it can step down  5. V signal to 3. 3. V signal and, if signal is sent in reverse direction it will step up the 3. V signal to 5. V. However, Bi Directional Logic Level Converter can be an expensive option for such task because we are only worried about the RX pin of NEO 6. M and I did not have a converter around to try out. Connecting two 1. N4. 14. 8 diods in parallel which gives a voltage drop of around 1. V is another option. Final Solution. The optimal solution was to use a voltage divider circuit. Nice voltage divider calculator is available at Raltron as well. After few calculations it was decided to use 4. K as R1 and 1. 0K as R2. Given input voltage of 5. V, mentioned voltage divider will give around 3. V which is well above the minimum logic level. Note Same applies to USB to SerialTTL adapters. If you are using a USB to SerialTTL adapter, connect TX of GPS module to RX of adapter and RX of GPS module to TX of adapter through the voltage divider. Vcc can be directly attached if you are using GY GPS6. MV2 board with input voltage range of 3. V 6. V. Arduino Code  Serial Communication. Below serial communication logic will print modules output to Arduino Serial Monitor available in Tools menu of IDE. Software. Serial. Create software serial object to communicate with GPS. Software.

As GPS data is somewhat sensitive I have masked actual values, leaving headers as they are. If you are using USB to SerialTTL adapter, please follow Pololus Guide on Communicating via the USB to TTL Serial Adapter using Putty. NMEA National Marine Electronics Association Data. Values printed in the previous experiment are called NEMA Data. More details about NEMA data is available at http www. For an example GPVTG seen in screenshot stands for vector track and speed over ground, while GPRMC stands for minimum recommend data. Example breakdown of GPRMC is as follows GPRMC,1.

U center is an GUI interface usable with U blox GPS modules to record, visualize and analyze GPS data. Download u center from the official web site. Close any open Putty sessions with GPS module or Arduino serial monitors. After installation u center, go to Tools menu and select Arduinos or USL to Serial devices COM port from Port list. U center should now display GPS readings in the right pane. It is also possible to use Google Earth option available in View menu to plot coordinates on map. Arduino Code Tiny. GPS library. Once library is installed in Arduino IDE File menu, Examples section you will find Tiny. GPS library and withing examples you will find testwithgpsdevice example. Open the example and change ss. Tiny. GPS library will process NMEA data and print a formatted output on in the serial output. Data processed by Tiny. GPS library can be used in other applications to easily extract important GPS information including Latitude, Longitude, Speed and Altitude.
