Moreover, new UMTS/HSPA module Quectel UG95 is pin-compatible with GSM/GPRS module M95 thus offering extraordinarily simple way to migrate to 3G without a PCB redesign.

To have a possibility to choose a component on a given PCB place according to our wish is certainly advantageous. For example in audio equipment to use a simple operating amplifier (for less demanding applications) or in other case to use a pin-compatible high-end operating amplifier for more demanding applications (on the same PCB position). This compatibility is common in some fields, in other ones not that much …

In a segment of GSM/GPRS/UMTS modules is this compatibility a sort of an exception, so arrival of the new Quectel UG95 module on the market can be an interesting solution how to use the same design for smaller GSM/GPRS/EDGE connection (with the M95 module) and also for a substantially faster UMTS/HSPA connection with the UG95 module.

Do you use 2G module M95 and you wish for a higher transfer speed?

UG95 offer extraordinary possibility to design your device able to work with M95 or also with UG95 module. UG95 features more pins than M95 but their position is compatible, so at a PCB design it´s possible to place all pins on a PCB and their real use will depend on whether you´ll use M95 or UG95.In result it´s possible to assemble the same PCB with M95 or UG95 module according to given application requirements.

UG95 is based on a new Intel XMM6255 chipset. In general, UMTS/HSPA transfer offers not only a higher transfer speed of pictures and data but mainly higher reliability of connection even in hazard conditions. That can be very important for critical applications like telemetry, process control, security and similar. Because from a new module we usually expect enhanced functionality, even in this field the UG95 has what to offer, for example:

  • rich set of internet protocols – TCP/UDP/PPP/MMS*/SMTP*/FTP*/SSL* (*-in development)
  • standard industrial interfaces – USB 2.0/UART/I2C/PCM
  • high sensitivity and top-class audio algorithms, digital audio output (PCM)

New module is available in a form of the module itself – UG95EA-02-NCH-STD (suitable for a mass usage into a target appliance) and also in a form of a known „adapter board“ UG95-TE-A mainly intended for development using the UC20EVBKIT development kit.

Detailed information will provide you the UG95 presentation, UG95 specification and the document Quectel UG95&M95 compatible design.

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.

The highest communication speed UMTS/HSPA+ and an easy communication via USB make the new module ideal for M2M applications.

Fast data transmission is becoming an inseparable part of devices for automotive industry, measuring, tracking, security systems, wireless terminals (POS), mobile computers etc.

When we´re choosing a module for above mentioned segments, it´s surely worth if the module also offers somewhat so to say “extra”. In case of the UC20 module it´s true, because there´s probably no parameter, which would the UC20 not meet and when you look closer at the datasheet, you´ll also find another functions like for example 2x 15 bit AD converter and other. A big advantage of the UC20 is, that it supports a fast transmission even outside of the 3G networks thanks to a dual mode (+ Multi-band) for WCDMA but even GSM with a support of GPRS/EDGE Multi-slot Class 12. A considerable benefit are also the Windows USB drivers (Linux and Android drivers are in development).

  UC20 can air itself even with a high sensitivity and a high integrity of transferred data even in adverse conditions. For a development support, there are also available reference examples – UC20-reference design as well as UC20-Compatibility design regarding HW compatibility of UC20 with the M10 module.

All package (12x pdf) of software user guides can be downloaded on this link (11MB). Detailed information will provide you the documents UC20-Specification, UC20-Presentation and UC20 Hardware design.

For many applications can be beneficial the UC20 module on a PCB in a form of the Mini PCIe card. Also available is the UC20_EVB development board.

All in one GSM 3G module Quectel U10 simplifies schematics and shortens testing time thanks to a quantum of built-in interfaces. If you´re searching for a module for transfer of data, voice, video, SMS and MMS, which has everything imaginable already built-in, then the Quectel U10 is the right solution for you.

Unbelievably many functions, supported protocols, built-in interfaces and other features are provided by the new 3G module Quectel U10. Thanks to this, in the most of applications it isn´t necessary to connect any other interfaces, what decreases the production cost of a target device. Only the list of features itself would occupy the whole article, that´s why we will mention at least some of them. 

The module supports dual mode and is multi-band (WCDMA & GSM) and a UMTS (HSPA) high-speed data transfer, further supported even by a high-speed USB 2.0 interface and three UART channels. CMOS camera interface with an 8 Mpx resolution enables a direct camera connection without other extra costs. All necessary can be stored into a directly connectable SD card with up to 32 GB capacity. To gain a Bluetooth communication, it is only necessary to connect an antenna to the U10. The U10 module also contains a control circuit for Li-ion battery charging, what is convenient in mobile applications, as well as when using a battery as a backup source. RIL (radio interface layer) driver for WinCE6.0 and a USB driver for WinCE 6.0, Win7/XP and Linux 2.6 further simplify a communication and connectivity. Excellent sensitivity, advanced audio algorithms and video codecs contribute to universal usage of the U10 module. So that it was possible to use all functions without limitations, a given circuit should have a wide operating temperature range – U10 meets even this requirement at 100% and has a guaranteed functionality in range from -40 to +85°C. Connection of the U10 to a PCB is very simple, by an SMD connector (board to board). The module naturally enables to use SIM cards of any GSM operator. U10EVB-KIT development kit is also available for a development support.

Basic information will provide you the U10 module specification and the Quectel U10 presentation. Detailed information will provide you the U10 Hardware Design, U10 AT Commands set, U10 EVB kit user guide and the video call application note.

U10, as well as U10-EVB kit are available directly from our stock. Guide price of the U10 module is 50 EUR at purchase of 1 pcs. Upon request we´ll let you know the exact price for your project.
