Kiváló minőségű SIM808 GPRS/GSM GPS Shield 2 az 1-ben Shield GSM GPRS GPS fejlesztőkártya SIM808 modul Arduinohoz
High Quality SIM808 GPRS/GSM GPS Shield 2 in 1 Shield GSM GPRS GPS Development Board SIM808 Module for Arduino
SIM808 a new generation of GSM, GPRS, GPS, bluetooth (optional)
SIM808 GSM/GPRS module, is a four frequency for the castle hole encapsulation Its performance is stable, compact appearance, high cost performance, can meet the various needs of customers
 
A, SIM808 is introduced
 
SIM808 working frequency for GSM/GPRS / 1800/1900 850/900 MHZ, can realize low-power transmission of voice, SMS and data information
 
Main features:
 
The four frequency MHZ 850/900/850/900
SMS
FTP/HTTP, embedded TCP/UDP protocol
DTMF detection, bluetooth 30 (optional), USB interface
Second, Aruduino SIM808 shields hardware is introduced
Power interface support 5-20 v voltage input, pay attention to the voltage of 5-9 v, can provide not less than 2 a power adapter current; Support the lithium battery (36-42 V)
For TTL level serial communication interface Fully compatible with the Arduino and compatible with other 5 V, 33 V, 285 V system
Can choose to use through the jumper cap hardware serial port (D0 D1) or software serial port (D7 D8)
Support the MICRO SIMCARD
Support four headphone jack (I type)
Update SIM800C firmware support via USB or serial port
Can be upgraded to a bluetooth version of the development board
Onboard TVS diode, SIM card protection IC, two 100 uf tantalum capacitors and so on a variety of ways to make the stable development board performance
Second, Aruduino SIM808 shields software is introduced
 
By TTL level a serial port communication with external systems, the default can communicate directly with 5 v system directly, without having to level the match And 33 V, 285 V system communication, to do a bit of hardware processing We will do detailed introduction on the user manual
Communication interface (command) for the AT command, which is control module function is realized through the AT command, such as: control module to make calls using ATD * * * * * * *; (* phone number) for each other We will provide a complete set of the AT command
In addition, we will provide the common features of some course of C program
