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.
