Microduino-GPRS/GSM

Language	English

Microduino-USBHOST Microduino GPRS/GSM module plug in the SIM card and use some simple instructions to make Microduino core board connected to the Internet, and then send, receive text messages. Features ESD protection； Uses USB powered or lithium battery solution； Supports automatic baud rate detection； Sends AT command and date via serial； Small, cheap, stackable, opened platfrom; Open source hardware circuit design, compatible with the Arduino IDE development environment for programming; Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly. 2.54 pitch row female connector for easy integration into breadboard. Specifications Uses SIM800L module to support four bands GSM/GPRS, working band is：GSM850、EGSM900、DCS1800 and PCS1900MHz. Electrical characteristics Working voltage：3.4V ~4.4V； Under Sleep mode, current consumption is 0.7 mA GPRS data GPRS data transfer up to 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 debug Supports standard full-function serial, and transmission rate from 1200bps to 115200bps;； Supports GSM 07.10 protocol serial multiplexing function； Two Main Compoments: 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 mudule SIM800L：文件:SIM800L.pdf SIM card base plant：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 the text message using library's example program. Prepare Work Prepared hardware：Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery； Prepared software: GSM library, Arduino IDE (1.0.3 release and upper)； Uncompress the zip folder to libraries of Arduino IDE； Connect the Microduino FT232R and PC using USB cable to download program and serial monitor； USB data cable or lithium battery to power Microduino GSM module and press the power button to make Microduino GSM boot, about maintaining 4S, turn on lights to indicate a successful boot. Debug Open the example program SendSMS from examples folder； After compiled, select the board "Microduino Core (Atmega328P@16M,5V)", download directly； Opne the serial monitor, set the baud rate, and set to the line and press enter, will print "SMS Messages Sender"; Input is completed, press enter, it will prompt you to input the sent content, Input is completed, press enter, you can see the text message sending progress. After completed, displays "COMPLETE!". Bug History Picture Microduino-GPRS/GSM Front Microduino-GPRS/GSM Front Microduino-GPRS/GSM Front Microduino-GPRS/GSM Front Video
