SIM900/A V3.8.2 DATASHEET Tech Support: 15124532672@163.com SIM5320E 3G MODULE Sim5320E is a GSM/GPRS module. You can send a message, make a call, transfer data though the GPRS or something else.
SIM900/A V3.8.2 DATASHEET Tech Support: 15124532672@163.com Overview This SIM5320E V3.8.2 module has a set of TTL level serial interface, a set of power supply interface. Besides, there are two set of antenna interface on this module, and one is designed for GPS and the other is for GSM/GPRS. Basic features Arduino 51 STM32 AVR MCU compatible Prototype expand The frequency: 850/900/ 1800/1900 /WCDMA 900/WCDMA2100 MHz. Power supply range: voltage is 4.6-5.
SIM900/A V3.8.2 DATASHEET Tech Support: 15124532672@163.com The description of 1*6 pins: 5V GND VMCU RST TXD RXD Use the TTL interface connect with a MCU MCU SIM5320E MOULE TXD SRXD RXD STXD DC power positive pole VMCU GND GND POWER(4.6-5.2v) 5V Notice that: 1. The pin of VMCU is used for compatible the TTL interface. When the high level of the MCU is 5v like the 51 MCU, we should connect the DC5V to VMCU, when controller is 3.3V like the stm32 MCU, the VMCU should connect the DC3.3V.
