| 1 | E611-900NW20S | The E611-900NW20S module is a long-distance wireless module developed by Ebyte that integrates long-distance image transmission and data transmission. It has a transmission rate of 16Mbps, can transmit 4 channels of 1080p video, and can also transparently transmit the network port and serial port at the same time. It works in the 850MHz~930MHz frequency band, and the maximum RF transmission power is 20dBm. |
| 2 | Network port | 10/100M Ethernet interface (RJ45). |
| 3 | USB to UART interface | The Type-C USB interface can be used as the power supply interface of the development board, can be used to burn firmware to the chip, and can also be used as a communication interface to communicate with the chip through the onboard USB to UART bridge. |
| 4 | Test resistance | Users can test the current through this resistor, which is a 0Ω resistor. |
| 5 | Pairing button | Master-slave pairing button, the user needs to press the host button at the same time until RSS1~3 and CON light are on, indicating that the pairing is successful. |
| 6 | Mode switch button | Master-slave mode switching button. |
| 7 | Antenna interface | SMA-K。 |
