SIM800C a new generation of GSM, GPRS, bluetooth (optional)
SIM800C 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, SIM800C chip is introduced
SIM800C working frequency for GSM/GPRS / 1800/1900 850/900 MHZ, can realize low-power transmission of voice, SMS and data information.SIM800C size17.6 * 15.7 * 2.3 mm, can apply to all kinds of compact product design requirements.
Main features:
- The four frequency MHZ 850/900/1800/1900
- SMS
- FTP/HTTP, embedded TCP/UDP protocol
- DTMF detection, bluetooth 3.0 (optional), USB interface
Second, SIM800C shields hardware is introduced
- Power interface support 5-26 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 (3.6-4.2 V)
- For TTL level serial communication interface.Fully compatible with,At the same time compatible with other 5 V, 3.3 V, 2.85 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, SIM800C 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 3.3 V, 2.85 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
SIM800C shields shipping list
- GSM antenna * 1 antenna (PCB)
- Development board * 1
