SIM800H GPRS Shield

Description

With popularization of the concept of the Internet of things (IoT), more and more people want to know and make their own IoT device . The common WiFi cannot satisfy the mobile application scenarios, while the emerging NB-IoT network has a limited coverage area, so the most popular 2G network becomes one of the best choices at present. DFRobot has updated the former GSM/GPRS expansion board, using the same series SIM800C GSM/GPRS chip as Mobike, in order to provide stable and reliable IoT links. A user may send AT instruction through UART communication interface, so as to make a call, send a short message and realize GPRS remote data acquisition, etc. SIM800C GPRS/GSM expansion board is encapsulated by Arduino standard, and can be externally connected with Arduino UNO , Leonardo and other controllers. The expansion board is externally expanded with TX&RX interface by jumper. Communication can be connected by soft serial port for convenient development. The built-in Bluetooth 3.0 wireless communication function may cooperate with mobile phone to realize point-to-point communication, and see SIM800C User Manual for more advanced features.
