R800C GSM/GPRS HAT for Raspberry Pi

The R800C GSM/GPRS HAT is a handy, low-power Raspberry Pi HAT which has multi-communication functionalities. It is small in size to easily implement into your next project, uses very little power, and has many functions including, making calls (applicable to countries or regions with 2G network coverage), sending text messages and surfing the internet wirelessly.

It comes with a 40-Pin GPIO header to go on your Raspberry Pi/ Zero, and a UART interface to connect to Arduino/STM32. A 3.5mm jack is included for use with headphones or a microphone, a SIM card slot that supports any 1.8V/3V SIM card, online development resources and a manual for ease of use.

Note: The Raspberry Pi and the Zero are NOT included

Features

• Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards and Jetson Nano
• SMS, phone calls, GPRS, TCP/IP, DTMF, HTTP, FTPl, etc.
• UART interface, for connecting controller boards like Arduino/STM32
• Onboard voltage translator, 3.3V by default, switch to 5V via jumper
• 2x LED indicators, easy to monitor the working status
• SIM card slot supports 1.8V/3V SIM card
• Baudrate: 2400bps ~ 115200bps (115200bps by default)
• Control via AT commands (3GPP TS 27.007, 27.005, and SIMCOM enhanced AT Commands)
• SIM application toolkit: GSM 11.14 Release 99
• Comes with online development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
