Ebyte CC3200 RS232 RS485 wi-fi data transmitter receiver 802.11b/g/n 2.4ghz industrial wifi serial server converter
[Frequency]：2.402~2.484GHz
[Power]：20dBm
[Distance]：0.3km
[Interface]：RS232/RS485
[Introduction]：Ebyte E103-W02-DTU realizes two-way transparent transmission of RS232 or RS485 serial port and wireless WiFi data. The traditional serial device has the function of TCP/IP network interface immediately, which greatly expands the communication distance of the serial device.

| 7 | ANT | Antenna (SMA-K,external thread and internal hole, 50Ω characteristic impedance) |
| 8 | WiFi | Indicator light of WiFi connection status, it lights up when connected and dies out while disconnected. |
| 9 | LINK | Indicator light of socket connection status, the LINK indicator lights up when connected and diesout while disconnected. |
| 10 | STAT | The STAT indicator lights up when entering SmartConfig mode and flashes three times while factory setting recovered. |
| 11 | Program | Burning simulation mode selection, default as high; when it needs to redownload software, please put the switch to low. |
| 12 | Restore | Factory setting recovery selection, it is default as high; when it factory setting needs to be recovered, please put the switch to low and then power on, it will be recovered to factory settings after the STAT indicator flashes three times. The module will inspect the pin when starting on, if the module has already been started,recovery will not be implemented by putting the pin as low. |
