d-u3G v1.13 series revision 2 - ARDUINO & RASBERRY PI micro 3G shield / board, our latest released product, compact as 1.35"x1.57"(34.29x39.88mm) and with weight around 10g, it is probably the most compact 3G module board on market.
d-u3G series it is pin to pin compatible with our 4G/LTE shield (l-LTE shield series), with our modular GSM shields (c-GSM shield series and h-nanoGSM shield series) and together, are parts of a bigger family build on top so call "plug-able boards concept".

d-u3G series has been released without performance compromises and brings to you the best market solution at reasonable cost and becomes the reference for this new product class. It is designed and manufactured in EUROPE by R&D Software Solutions team -awarded in 2006 with the GST SSC Bronze Award.

d-u3G v1.13 series integrates in this format the following main features:
  • USB serial connectivity adapter with RaspberryPI, Windows and Linux. USB connection, offers multiple serial ports support for concurrent application/threads communication.
  • 2.8-5V auto-level digital interfaces (UART TX+RX / RESET / POWER ON-OFF / RI / STS / RTS / CTS / SLEEP), for direct connection with Arduino boards, Raspberry PI or any other 2.8V up to 5V micro-controller board
  • build in Lithium Polymer battery charger. Depending on powering schema, all boards version can be used with or without LiPol battery.
  • Plug-able accessories as: switching power supply (stand alone or with LiPol usage), (future) u-controller boards, other.
  • POWER ON and RESET push micro switches
  • Standard size SIM support
  • uFL or SMA F antenna connector
  • POWER ON and RESET push micro switches

The d-u3G series answers at your needs for a fully lightweight, integrated, fully functional and affordable cellular 3G modem shield / platform. Smart complete design of the d-u3G micro shield brings you the flexibility and easiness in integration, wherever your platform and application. Beyond ARDUINO / RASPBERRY PI / others hobby / DYI platforms integration, the d-u3G series can be easily and in a time manner incorporated into your equipment regardless your previous experience in modem technology. The d-u3G series represents your best choice for usage into a wide range of designs requiring robust 3G mobile communications and reliable performance.

Manufactured in EU.
