MIKROE-2296

Page 1 of 2 3G click From MikroElektonika Documentation 3G click is a mikroBUS™ add-on board with Quectel’s UG95 3G UMTS/HSPA module. The board has a rich set of components to simplify development: an SMA connector, earphone/microphone jack, MicroUSB port, as well as a SIM card slot. The network protocol stack includes support for TCP, UDP, PPP, MMS, FTP, SMTP, SMTPS, HTTP, HTTPS, PING, and SSL. 3G click communicates with the target MCU through the mikroBUS™ UART interface (RX, TX), with additional functionality provided by STAT, PWRKEY, RTS, R1, and CTS pins. The board is designed to use either a 3.3V or a 5V power supply. 3G click Features and usage notes Due to the nature of the protocol, 3G click comes in two different versions. The Europe and Australia version operates on the 900/2100@UMTS, 900/1800@GSM frequency band, while the USA version works on 850/1900@UMTS frequency band. The boards are otherwise identical. An onboard jumper allows you to choose the I/O voltage levels between 3.3V and 5V. Signal LEDs show the status of the data transmission.
