Using GPRS module is the implementation of the project are: more common wireless meter reading, the vehicle navigation and positioning, wireless monitoring, smart home (such as data information in the network can get home) in terms of GPRS data transmission to connect to the Internet is charge flow, low cost, while texting, in accordance with article number to collect, the high cost. The development board can realize the function: 1). Send and receive SMS/MMS (long-term technical support) 2). Voice calls (long-term technical support) 3). GPRS communication (long-term technical support) 4). Can be an external various microcontroller (3.3 V to 5 V) controls the development board (long-term technical support) Let's make a brief introduction of the basic knowledge of GSM module: 1). GSM development board can be done. you can send and receive calls, text messages, send and receive MMS, GPRS network data transmission (similar to mobile Internet). 2). Through what makes GSM development board to achieve the above functions: can through the computer, but can be by outside access to the single chip microcomputer. Have a dedicated computer software (GSM serial debugging assistant), single chip microcomputer to burning we form a complete set of procedures. To pick up good cable according to our specifications. 3). What is the AT command In order to control the function of the GSM module, a few famous mobile phone module manufacturers have developed a set of general aspects of simple instructions to control the GSM module, such as call 10086 the AT command is: ATD10086; The user just sent via a serial port to the GSM development board ATD10086 characters; + a carriage return (a/r), the module will call 10086 number. SIM900 Sim900 module simcom company a classic GPRS model, has a very high cost performance. Widely used in mobile phones, pdas, wireless data transmission, etc. Sim300 is 60 pin board connector dual-band GSM/GPRS module solution. Standardized interface module with industry, low power consumption, can through the GSM/GPRS / 1800/1900 850/900 MHZ communication network transmission voice, SMS, data and fax. As long as engaged in mobile phone development, wireless transmission of the staff on sim300 the understanding of the classic series have many, many developers are starting with this product contact wireless transmission module, the reason is very simple, because sim900 easy to learn, high cost performance, simple hardware interface don't want to other modules need complex peripheral circuit, software as long as you understand serial transmission, with reference to the AT command can operate on him. Wireless transmission is learning, the best choice for mobile development. SIM900 main characteristic parameters: Working voltage:Single power supply voltage,3.4--4.5V. low-power modes:Static mode, the working current typical value of 2.5 mA. Work frequency band: 1). SIM300 has three phases:EGSM900,DCS1800,PCS1900,Spectrum frequency can be made of the AT command set, the default frequency band is EGSM900 and DCS1800, 2). Compatible with GSM Phase2/2 + GSM type:Small mobile base station(MS) Power consumption of the launch: 1). In frequency EGSM900 CLASS 4 2 w 2). .In frequency DCS1800 and PCS1900 CLASS 1 of 1 w GPRS connectivity: 1). GPRS much time slot level 10 2). GPRS mobile station B Operating Temperature: Normal working temperature: - 22 °C ~ + 55 °C Limit working temperature: - 22 °C ~ 20 °C and + 55 °C ~ + 70 °C Storage temperature: - 40 °C ~ + 80 °C GPRS data transmission: The biggest 85.6 KBPS GPRS downstream data transmission GPRS uplink data transmission maximum 42.8 KBPS Coding scheme: CS - 1, CS - 2, CS - 3, CS - 4 SIM300 support PAP agreement, this agreement is typically used for the PPP connection SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US 1)All items will be shipped to your paypal address .Please update your latest address when you check out,and please make sure to provide us with correct,precise and detailed shipping address. 2)Most of the items will be shipped via Hongkong Airmail/Singapore Airmail .To US customers,we will send the package via E-packet . 3)All items will be shipped in 1-2 business days (excluding Sat,Sun & Holiday) after payment received and cleared.
