Indicators

PWR

Power: When there is normal supply to the board, the indicator keeps on.

STATUS

SIM900 status: When SIM900 works normally, the indicator keeps on.

NET

SIM900 network status: used to indicate network status, the working status of the indicator is as below:
Network indicator status SIM900 working status
OFF SIM900 does not work
64ms on/800ms off SIM900 does not find network
64ms on/3000ms off SIM900 registers the network
64ms on/300ms off GPRS communicates

Keys

SIM900-PWRKEY

SIM900 powering-on key: Keep pressing the key for more than 1 second, SIM900 will be powered on; keep pressing the key for more than 1 second after the board is powered on, SIM900 will be powered off.

SIM900-RST

SIM900 resetting key: press the key, SIM900 will be reset.

Note

The module does not support hot swapping.
