Brief introduction of TC35I

TC35i The new Siemens industrial GSM module is an industrial GSM module that supports Chinese short messages. Working in EGSM900 and GSM 1800 dual frequency bands, the power supply range is 3.3~4.8V DC, the power consumption-sleep state is 3.5mA, the idle state is 25mA, the emission state is 300mA (average), and the peak value is 2.5A. It can transmit voice and data signals, and the power consumption in EGSM 900 (Class 4) and GSM1800 (Class1) is 2W and 1W respectively. It is connected to a SIM card reader and an antenna through an interface connector and an antenna connector respectively. The voltage of SIM is 3V/ 1.8V, and the dATa interface (CMOS level) of TC35i can transmit instructions and data in both directions through at command. Optional baud rate is 300bb/s ~ 1 15kb/s, and automatic baud rate is 1.2kb/s ~ 165438. It supports SMS (Short Message Service) in text and PDU format, and can be restarted and resumed by at command or shutdown signal.
