Track and Trace anything with the Arduino AnyTracer of only 25 x 25 mm! It is the smallest, complete GPS GSM tracker in the entire world.
A movie is not necessary here! The photos speak for itself. Together with the best Italian and Russian GPS specialists we managed to make the smallest complete GPS GSM tracker in the world. This tracker is only 25 x 25 mm! With the onboard STM32 microcontroller you can program it yourself with Arduino or online (!) with Mbed.org or in C using Keil or the opensource CooCox IDE. Almost anybody can do the programming with their own beloved platform.

Connectors M.2 also called as NGFF have a chance to become a widely used standard in computers, communication equipment and M2M applications.
The newest member of the data connectors family in our offer are connectors Attend series 123, so called NGFF – New Generation Form Factor connectors, also known as „M.2“. Their main advantage is implementation of PCI Express 3.0, Serial ATA 3.0 and USB 3.0. buses into one connector. The connector is considerable miniaturized and at the length of only 21.8 mm it has up to 75 pins ( 0.5mm pitch/ 50V/0,5A). M.2/ NGFF are designed as a future standard for SSD memory media, WiFi, Bluetooth, GPS/GNSS, NFC and other modules. As it´s not a “specialty” of one producer but it´s a connector designed as an international standard, their usage in your device can be advantageous thanks to a supposed easy availability even in the future. An important fact is, that connectors are produced with various keying (A-M). That provides a possibility to differentiate various modules on one board and prevents improper connection (PCIe x2, PCIe x4,…).
M.2 connectors are designed for a direct insertion of PCB, i.e. one part of a connection (M) is a PCB and another part is the connector (F). Connectors support various PCB widths – 12, 16, 22 and 30 mm. Depending on a type, M.2 connectors also enable a double-sided assembly of components on a PCB.
Another novelties from the Attend production in our stock are interesting types for SIM cards, as well as combinations 2xSIM(115L-AB380), 2XSIM + uSD (115M-AB360) and other, which can be found below this article.

By Boris Landoni @ open-electronics.org:
By coupling a standard NMEA GPS receiver and an Arduino board we created a super simple and effective Arduino GPS logger. This device allows you to trace the route taken by a person or vehicle (or any other moving object) by simply doing a periodic caching of location points coming from the GPS unit. As the logger saves the list of records (containing data on recorded positions) on a microSD memory card, you can then move the data onto your computer and keep track of your trip. You can use tracked data to help project such as OpenStreetMap to grow and include new areas (www.openstreetmap.org).

A group of students at Indiana university has built an Arduino-based distance measuring tool as their class project. It is a handheld device that measures the distance between any two points using the latitude and longitude coordinates (received from GPS satellite) of the points. It provides distance output in Yards and is useful for sports applications, such as in golfing to compute the distance between where a ball is hit and where it ends up.

Here’s Oscar Liang another Arduino GPS project, he writes:
Garlow stands for GPS Arduino Rechargeable Logger OLED Watch. The device gives GPS information which is logged on SD card and shown on a OLED display. It can be carried as a watch or simply used as a GPS data logger. The whole system is based on Arduino Nano, with a Lipo power management module which enables USB battery recharge.

New antenna 2J620P will provide you a high quality GSM and GPS signal at once, moreover with a very simple assembly.
Tracking of vehicles or goods is still more used what naturally results into a requirement for a suitable antenna. One of them can be the 2J620P. It offers a very simple and elegant solution, as in fact it is “2 in 1” – two antennas in one enclosure, each with a separate RG174 cable and SMA connector. Assembly is absolutely simple – by means of included double-sided foam pad. Also supplied is even a small towel filled by isopropanol for cleaning of a place of assembly as well as antenna itself.
2J620P has a 2.14 dBi gain for GSM and 26-28 dB for GPS. The GPS portion is equipped by an active amplifier, that´s why requires 2.7-5.5V/15-25 mA power supply. In many applications can be also advantageous a flat shape without any nibs.
Detailed description of the antenna can be found in the 2J620P datasheet.

New GSM/GPRS/GPS/GNSS modules Quectel offer also special functions, able to make your product exquisite.
Development in the field of communication modules is fast and there are still more segments for their applications. That´s why company Quectel always comes with novelties or at least with enhanced versions of existing modules. This is also the case of two novelties M95EB and UC15.
Module M95 is certainly familiar to you from several our articles like for example Even the Vodafone confirmed quality and reliability of Quectel M95 GSM module. M95 belongs to a TOP in the segment and recently we announced you an eCall support. Meanwhile, this version came to a mass production and we can easily differentiate it by the „EB“ suffix. New version M95EB also supports Dual SIM function (DSSS), what makes it extra reliable even for emergency systems and similar applications. A previous M95 as well as new M95EB are compatible and they will be on the market in parallel, that´s why company Quectel recommends to use the new version (EB) only for applications where you plan to use these new functions.The second novelty is the UC15 module (UMTS/ HSDPA), which is similar to UC15 in many respects, but it´s smaller (29x29x2.5mm) and it has only 66 pins. The main difference is that UC15 doesn´t support GPS/ GNSS and it´s also somewhat slower (upload). UC15 is cheaper than UC20 and in many applications it can represent a very interesting alternative for a very attractive price.
A comprehensive description and comparison of Quectel modules can be found in the Quectel brochure as well as in the datasheets in particular types.

With the rapid development of GPS (Global Positioning System) techniques, GPS gets wider application in many fields. GPS has features such as high precision, global coverage, convenience, high quality, and low cost. Recently, the use of GPS extends speedily from military to civilian applications such as automobile navigation systems which combine the GPS system, e-map, and wireless network. GPS is getting popular, and the market for GPS techniques is extending continuously.
UARTs provide serial asynchronous receive data synchronization, parallel-to-serial and serial-to-parallel data conversion for both the transmitter and receiver sections. These functions are necessary for converting the serial data stream into parallel data that is required with digital systems. Synchronization for the serial data stream is accomplished by adding start and stop bits to the transmit data to form a data character. Data integrity is ensured by attaching a parity bit to the data character. The parity bit is checked by the receiver for any transmission bit errors.
The circuit describes how to combine GPS into a navigation system by using a Philips 2-channel UART, the SC16C2552B. The SC16C2552B is a two channel Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 5 Mbit/s.

A new multi-band satellite antenna developed by Imec in collaboration with Septentrio was announced at the Mobile World Conference held recently in Barcelona, Spain. The antenna is a multi-band design capable of simultaneously receiving GPS, GLONASS, BeiDou and GALILEO satellite signals. The resulting receiver is capable of resolving its location to within 1 cm.
The antenna is paired with Septentrio’s credit card-sized AsteRx-m receiver, a dual frequency GNSS (Global Navigation Satellite Systems) receiver that provides centimetre accuracy while drawing less than 500 mW
