[Introduction]：EA01-D is an NB-IOT data transmission module developed by Ebyte for the purpose of realizing mutual data transmission between a serial device and network server merely by user simple setting. It supports B3, B5, and B8 frequency bands. The module is well-equipped with software and functions, covering most of the general application scenarios.
| No. | Pin | Description |
|---|---|---|
| 1 | RST | Reset, valid in low level |
| 2 | IO_RT | If low level lasts about 1 second, the factory settings will be restored and the automatic restart will take effect. |
| 3 | LIKA | Socket0 connection status indicator: corresponding to the onboard left LED light 1.High: Socket0 is successfully connected to the network server Low: Socket0 fails to be connected to the network server; |
| 4 | LIKB | Socket1 connection status indicator: corresponding to the onboard left LED light 2.High: Socket1 is successfully connected to the network server Low: Socket1 fails to be connected to the network server; |
| 5 | DATA | Socket data receiving and sending status indicator: When data is received by network or when data is received by serial port, the indicator light flashes, corresponding to the onboard left LED light 3. |
| 6 | NET | Device network status indicator: corresponding to the onboard right LED light 1.When the device is attaching to the network, it flashes rapidly;After the device is successfully attached to the network, it flashes slowly; |
