mga tol may nakaka alam po ba sa inyo about sa gsm sim900?

meron po akong 12v.2000mA na power supply (Charger)
di po ba ma sisira system ko nito pag sinalpak ko ang ganitong power supply?

(paki delete po pag mali ang location ng thread salamat)

5volts lang kadalasan ang supply nyan pagsinalpak mo ang 12volts masisira talaga

• Control pin all leads.
• A TTL level, compatible with 3.3V and 5V.
• The two antenna interface, the default SMA straight head, connector for IPXmini antenna.
• One way of speech interface, the way Mike interface.
• The control interface of each pin description:
• GND - GND
• SIMR SIM900A RXD, TTL level, can not be directly connected to the 232 level
• SIMT SIM900A TXD, TTL level, can not be directly connected to the 232 level
• RST - SIM900A reset, active low
• VCC_MCU when the SIM900A module and 5V TTL level communication, this pin is connected to DC 5V; when the level of communication of SIM900A and 3.3V TTL, this pin is connected to DC 3.3V.
• VCC5----DC 5V input.
• VCC4------DC3.5--4.5 input
• Onboard Resources:
• Serial port circuit(with protection)
• Antenna interface circuit(SMA bend female port)
• SIM card circuit(flip SIM slot)
