RPI GSM Adapter is an adapter which accomplished communication by the direct connection between Raspberry Pi GPIO and the GSM/GPRS Module-EFCom Pro. We designed two GPIO interfaces in parallel connection，therefore, RPI GSM Adapter can not only connect to Raspberry Pi GPIO，but also connect to the modules compatible with Raspberry Pi GPIO（like our RPI TFT LCD Adapter、RPI BRD Adapter）. In addition, for the circuit, we use the strong DC_DC external power supply, plus a toggle switch, so you can either choose the raspberry pie internal power supply, or select an external one.
Note:
When RPI BRD Adapter connected with Raspberry Pi GPIO, please make sure their pins are corresponding with each other.

- Compatible with GSM/GPRS Module-EFCom Pro
- Switchable and strong external power supply
- Unique design, more convenient for connection
- Dimension： 46.2mmx35.1mm
Applications：
- Communicate with GSM/GPRS Module-EFCom Pro
- Connect with modules compatible with Raspberry Pi GPIO
