Microduino-GPRS/GSM

Language	English

Microduino-USBHOST Microduino-GPRS/GSM module can get Microduino core board connected to the internet and achieve the function of sending and receiving messages when it is just inserted with a SIM card and follows some simple instructions. Features ESD protection; Capable of being charged by USB, li-ion or other power supply options; Support automatic baud rate detection function; Capable of sending AT instructions and data through the serial port; Small, cheap, stackable and open; Open hardware circuit design and Arduino compatible programming development environment; Uniformed Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors in accord with Microduino interface standard; Easy to be integrated to pegboards with a 2.45-pitch female header connector interface. Specifications Adopt SIM800L module to support four-band GSM/GPRS, whose working band is：GSM850, EGSM900, DCS1800 and PCS1900MHz. Electrical characteristics Working voltage：3.4V ~4.4V； The current consumption is 0.7 mA under the Sleep Mode GPRS data The maximum data transmission rate of GPRS is 85.6 kbps;； Build-in TCP/IP protocol； Encoding format：CS-1, CS-2, CS-3 and CS-4； Support Unstructured Supplementary Service Data (USSD) Serial debugging Support standard full-function serial as well as the transmission rate with a range from 1200bps to 115200bps; Support the serial port multiplexing function complying with GSM 07.10 protocol； Two Main Components: SIM800L module 文件:Microduino-SIM800L-Pinout1.jpg Microduino-SIM800L-Pinout 文件:Microduino-SIM800L-Pinout2.jpg Microduino-SIM800L-Pinout SIM card power and base plant 文件:Microduino-SIM-Pinout1.jpg Microduino-SIM-Pinout 文件:Microduino-SIM-Pinout2.jpg Microduino-SIM-Pinout Document Eagle PCB： 文件:Microduino-GSM.zip Microduino-GSM module SIM800L：文件:SIM800L.pdf SIM car power supply and the card base：文件:SIM800L.pdf Development You can use GSM library to test, https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_03_Microduino_GSM_SIM800L Note：This library only supports Microduino-core. Application Send short messages using the example program. Preparation Hardware：Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery； Software: GSM library, Arduino IDE (version 1.0.3 and higher)； Uncompressed the zip folder to libraries of Arduino IDE； Connect the Microduino FT232R and PC using USB cable to download program and monitor the serial port； USB cable or li-ion battery to charge the Microduino GSM module and press the power button for a long time to activate Microduino GSM for about 4 seconds. That the power-on indicator goes on shows a successful start. Debugging Download the test program: https://github.com/Microduino/Microduino_Tutorials/commit/25a821ba8894fb02d4b1560c9912450cc353b875 Open the test program, and then you need double check the following parameter: “#define NUM "13667928xxx"”：Need change to the number that receive message. “#define SMS_CEN "13010720xxx"”：Your message center for you own mobile phone number, you can find it in your phone. It isn't the necessary. If hit an issue during send a message, you can try it. Compile the program, select the board type "Microduino Core+ (Atmega644P@16M,5V)", download directly: Open the serial monitor, set the baud rate is 9600: Input "t", to send the message "wiki.microduino.cc"; Input "d", you can make a call, but can't finish a normal call, because no the speaker and microphone; Input "h", you can submit a HTTP request to get some data from network; Input "s", you can send the sensor data to network. 如果你使用Microduino Core调试，你需要用到软串口（TX1，RX1） If you use the Microduino Core to debug, must use the Software Serail (TX1,RX1) Use the Software Serial library #include <SoftwareSerial.h> SoftwareSerial mySerial(2, 3); // RX, TX Change the Serial1 to mySerial, it should be ok。 If you use the Microduino CoreUSB to debug, you only need to change the serial to serial 0 (TX0,RX0). 文件:Microduino-SIM800L-Pinout2.jpg Microduino-SIM800L-Pinout FQA Does this module can be used to make a voice phone? Any voice pin was picked out? This module can’t be made a voice phone, because it doesn’t have pin. Does this module can work with Core+ module? Yes. Does this module can use Arduino GSM library? Yes. Does this module can use to 3G? No, it only supports GPRS and GSM. How to power on this module? There are two methods: Using the USB on attached module to supply the power, the voltage is 5V and the current MUST lager than 1A. Using Li-ion battery on attached module to supply the power, the Li-ion should be 3.7V. BM module can power on the Core module and other module, such as 10DOF, but don't suggest to power GPRS/GSM module, because it is a big power consumption module.
