The Raspberry Pi GSM Adapter is an adapter which accomplishes communication by direct connection between Raspberry Pi GPIO and the GSM/GPRS Module EFCom Pro. Elecfreaks 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 Elecfreaks RPI TFT LCD Adapter or RPI BRD Adapter).
Note: When a RPI BRD Adapter is connected with the Raspberry Pi GPIO, please make sure their pins are correctly aligned with each other.
- Compatible with GSM/GPRS Module EFCom Pro (not included!)
- Switchable to stronger external power supply
- Unique design, more convenient for connection
- Dimensions: 46.2 x 35.1mm
