MODULE GSM/GPRS SIM800F Module for GSM; GPRS; SMS; VOICE.
MODULE GSM SIM800F is a small GSM and GPRS module for connecting with various systems with microcontroller (e.g. arduino, ESP, Raspberry etc.) for communications over gsm or GPRS network and SMS messages. It also allows voice communications. It has integrated an RGB LED for viewing the state of the network. On the back is a micro sim card connector. Communications can be sent by RX and TX series lines or alternatively via USB. It has some header pins for easy connections.
