GSM / GPRS / GNSS / Bluetooth HAT for Raspberry Pi

Description

Overview

This is handy, low power Raspberry Pi HAT which features multi communication functionalities: GSM, GPRS, GNSS and Bluetooth.

It allows your Pi to easily make a telephone call, send messages, connect to wireless Internet, global position, transfer data via Bluetooth, and so on.

General

• Supports SMS, phone call, GPRS, DTMF, HTTP, FTP, MMS, email, etc.
• Support GPS, COMPASS, Glonass, LBS base station positioning, omni-positioning
• Bluetooth 3.0, supports data transferring through Bluetooth
• Onboard USB TO UART converter CP2102 for UART debugging
• 6x LEDs for indicating the module working status
• SIM card slot for 1.8V / 3V SIM card
• RTC with backup battery holder
• Baudrate auto detection (1200bps ~ 115200bps)
• Control via AT commands (3GPP TS 27.007, 27.005, and SIMCOM enhanced AT Commands)
• Supports SIM application toolkit: GSM 11.14 Release 99
• Comes with development resources and manual (examples for Raspberry Pi/ Arduino / STM32)
