LTE CAT M1? NB IoT? LTE CAT 4? LTE CAT 1? UMTS? GSM? Just u-GSM! But, why "u"? "u" because it's unified, ultimate, unique, unbelievable and ... unobtainable, until now! ALL deployed GSM standards are supported! No need for different designs, just same form factor, same integration approach regardless the integrated modem, just this amazing u-GSM v2.19 by

Not only all GSM standards are supported, but popular SBCs [Raspberry PI and BeagleBone Black are supported directly through integrated interfaces] and micro-controller shields [Arduino, Teensy and any other 3-5V MCUs] are too.

In addition to RPI and BBB embedded interfaces, the u-GSM shield shares the same ITBMM interface [ modular modem interface] with all our previous modular modems:
- 4G / LTE CAT4 and 4G / LTE CAT 1 versions (l-LTE shield),
- 3G / UMTS version (d-u3G shield),
- dual SIM GSM only version (c-uGSM dual SIM shield) and
- GSM + BTH 3.0 version (h-nanoGSM shield).

Through the ITBPMM interface, following accessories may be plugged:
- 4V and 5 V switching power supplies (g-SPS v1.02 LiPOL and DDRV),
- i-hatGSM3G (RASPBERRY PI adapter board for ITBP modular modem shields) and,
- j-328GSM3GLader (Arduino Micro / Arduino Mini / Arduino Nano adapter board for ITBP modular modem shields).

Arduino C, Raspberry PI [USB drivers, Python and shell script] and BeagleBone Black [USB drivers, Python and shell script] software support.

u-GSM shield v2.19 integrates in this format the following main features:
  • Raspberry PI, Beagle Bone Black and ITBPMM embedded interfaces,
  • The u-GSM board can be trimmed by end user. Standard, the PCB perfectly fits perfectly with Beagle Bone Black. By trimming, the PCB will fit the Raspberry PI form factor, or the ITBPMM format.
  • The USB port is available via USB soldering PADS and via standard USB mini B.
  • External SIM support via soldering PADS [also having embedded nanoSIM holder].
  • VIA pads for super-capacitor [or additional capacitor] soldering.
  • Modem power separation circuit embedded [enables modem advanced sleep mode].
  • Solder jumpers for alternate configuration.

Not forget to mention about oldies but goldies features [some of them coming from l-LTE, d-u3G, c-uGSM and h-nanoGSM designs] like:
  • high performances GNSS engine embedded [only BG96, EG91A and EG95A versions] with parallel GPS and Glonass satellites interpolation for best accuracy and signal sensitivity. Supports active and passive GNSS antennas.
  • ITBPMM interface - digital/powering interface compliant modular modem interface
  • 3-5V auto voltage support for UART and control GPIOs [ENABLE, RESET, STATUS and RI]
  • embedded LiPo battery / Li-Ion battery / super-capacitor charger --> u-GSM can be powered directly from RPI / BBB 5V PINs!!!, from USB or external 5V 150mA power source
  • supports direct powering from 4V, 650mA sustained and 2A pulse capable power supply[no battery, no super-capacitor required]
  • RESET push switch integrated [modified function for BG96 variant]
  • ITBPMM, USB and external SIM interfaces have BIG SIZE SOLDERING PADS
  • Compact design [main partition -wo RPI&BBB interfaces]: 27 x 45mm
  • Slim weight: around 10g
  • uFL or SMA F antenna connector [due to mechanical reasons, SMA F versions can be connected to RPI or BBB only via ITBPMM interface]

Smart complete design of the u-GSM modular shield brings you the flexibility and easiness in integration, wherever your platform and application.

Proudly designed by R&D Software Solutions and released in 2018.

Manufactured in EUROPE.
