I have received the PCB from my transmitter board from PCBWay. Then I soldered the components using my own hot plate. The final look is really awesome, attaching a few pictures for the same.

The main features of the PCB are

1. 2 Battery Options: Either 18650 battery directly into the slot or LiPo battery through the battery JST connector

2. Solar charging port: " SOLAR PANEL "  screw terminal

3. USB-C charging port - USB-C is given for quicker charging of the battery in case of low sunlight for a long time.

4. 6 x I2C ports for hooking up a variety of sensors

5. 2x RJ11 ports for connecting the Wind and Rain Sensor

6. Additional port for Air Quality Sensor ( PMS5003 )

7. Screw terminal to connect the DS18B20 temperature probe 

8. Programming port for uploading the sketch by using a UART serial programmer
