c-uGSM v1.13 series revision 2 - ARDUINO & RASBERRY PI micro GSM shield / board, one of our latest released product, compact as 1.25"x1.57"(31.75x39.88mm) and with weight around 10g, it is probably the most compact GSM module board on market.
c-uGSM series it is pin to pin compatible with our 4G/LTE shield (l-LTE shield series), our 3G/UMTS version (d-u3G series), our single SIM GSM + BTH 3.0 nano shield (h-nanoGSM shield) and together, are parts of a bigger family based on "pluggable boards concept".

c-uGSM 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.

c-uGSM v1.13 series, in this compact format, integrates following main features:
  • USB serial conectivity adapter with RaspberryPI, Windows and Linux. The USB connection offers, for Raspberry PI usage, the posibility to leave free the serial connection for other application/shields as GPS.
  • 2.8-5V auto-level digital interfaces (UART TX+RX / RESET / POWER ON-OFF / RI / STS / RTS / CTS), for direct connection with Arduino boards, Raspberry PI or any other 2.8V up to 5V micro-controller board
  • build in Lithium Polimer battery charger. Depending on powering schema, all boards version can be used with or without LiPol battery.
  • Pluggable accesories as: switching power supply (stand alone or with LiPol usage), (future) u-controller boards, other.
  • POWER ON and RESET push micro switches.
  • TWO standard size SIM support* as default hardware.
  • uFL or SMA F antenna connector
  • POWER ON/OFF and RESET push micro switches

The c-uGSM series opens to you the access to a fully light weight, integrated, fully functional and affordable cellular GSM modem shield / platform. Smart complete design of the c-uGSM 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 c-uGSM series can be easily and in a time manner incorporated into your equipment regardless your previous experience in modem technology. The c-uGSM series represents your best choice for usage into a wide range of designs requiring a robust GSM mobile communication and reliable performance.

Manufactured in EU.
