GSM3 Click Board

IC/Module: SIM800H Quad-Band GSM/GPRS Module

The miniature SIM800H quad-band GSM/GPRS module is intended to offer a lot more than the conventional voice, SMS/MMS and data transmission. The added features mainly include Bluetooth (3.0+) and FM radio receiving in a wide range of 76-109 MHz with a 50 kHz step. With a slim and compact profile, it can be easily embedded to any user design.

Added Functionality over Conventional Capabilities

Bluetooth: GSM3 click supports Bluetooth and is provided with a 2.4 GHz active antenna for that purpose. A SMA connector for an external GSM/GPRS quad-band antenna is also provided. Note: Quad-band antenna sold separately.

Audio Input/Output Connection Pad: GSM3 click is provided with a connection pad with an audio input/output. The connection pad has two pins for earphones, which can also be used as an FM antenna, as well as one pin for a microphone, plus GND.

Communication with the Target Board

GSM3 click exchanges data with your target board's MCU through UART, but a total of eight mikroBUS lines are used for additional functionality. The mikroBUS lines include: Tx and Rx — UART, RST — Reset, GP1 — Status indicator, GP2 — RTS, GP3 — GPIO1, GP4 — PWRKEY, used to turn the module on/off, GP5 — CTS.
