Specification: * Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all countries across the world. * GPRS multi-slot class 10/8 * GPRS mobile station class B * Compliant to GSM phase 2/2+ * Class 4 (2 W 850 / 900 MHz) * Class 1 (1 W 1800 / 1900MHz) * Control via AT commands - Standard Commands: GSM 07.07 & 07.05 | Enhanced Commands: SIMCOM AT Commands. * Short Message Service - so that you can send small amounts of data over the network (ASCII or raw hexadecimal). * Embedded TCP/UDP stack - allows you to upload data to a web server. * RTC supported. * Selectable serial port. * Speaker and Headphone jacks * Low power consumption - 1.5mA(sleep mode) * Industrial Temperature Range - -40°C to +85 °C * Size:8.5x5.7x2cm(approx) 100% brand new and high quality The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module(They are all 2V8 logic) present onboard.

Specifications Bluetooth Protocol: Bluetooth Specification V4.0 BLE USB Protocol: USB V2.0 Operating Frequency: 2.4GHz ISM band Modulation Mode: GFSK (Gaussian Frequency Shift Keying) Transmitting Power: =4dBm Sensitivity: =-84dBm at 0.1% BER Transmission Rate: 6 kbps (asynchronous & synchronous) Security Feature: Authentication and encryption
Module stereo output, built-in Bluetooth antenna structure is simple, the power supply voltage is 3.7V~5V version selection, active speakers increase Bluetooth connection function. 7PIN output interface is spacing 2.54 through hole, 7PIN output interface is: + power, ground, left channel, right channel, mute, LED status indicator, reserved port.
The HC-05 bluetooth module can be set as a transmitter or receiver. You can combine this bluetooth module with your system: MCU, ARM or DSP systems, SOC systems.This module can build a connection to other modules in two ways: as a master or as a slave. Ex, a robot can be designed to be a master connected to a slave bluetooth module or as a slave board to make a wireless connection with a PC.
