  • Shield Arduino GSM/GPS/GPRS

Based on GPS GPRS / GSM SIM808 module, this shield can be used with Arduino (UNO, Leonardo, Fishino, NUCLEO, XNUCLEO) to create IoT projects (Internet of things) such as data acquisition, remote controls, GPS locators, etc. Supports calls and SMS (headphone jack and microphone available) - communication is via AT commands. It has a slot for micro SD card (not included), reset button, SMA connector and U.FL for GPS, GSM and Bluetooth antenna, status LED for power supply and GPS Fix.

Note: the UNO PLUS in the photo is NOT included.
