Description: The sim900a is a dual band module gsm 900 / 1800 mhz that supports voice call, sms and gprs. But it doesn 't have jack audio on board, which means you can' t hear or talk over the call. Feature: - power supply by 5v, powered by usb, for longer-term use better using its own 1a power supply with xh2.54-2p connector. - ttl 5v and 3v3 (yellow pin marked on board), compatible with arduino, stm32, raspberry pi, etc. - onboard rs232 is easy to debugging. On the left, white pin. - on the board there 's a led signal on the left. - top of the sim900a ic angle. On board reboot and restart pin, at the bottom of sim900a ic. - it has a mini ipx connector, but it hasn 't been held. - standard sma antenna connector. - serial port protected by tvs to prevent a surge in current or hv. - sim circuits have smf05c electrostatics releasing ic. - packages include antennas and dc jacks. - the size of the board is 5
