June 8th : Design the idea and working of project

I figured out how should my Transmitter module will work and how can i build this.I researched a lot about transmitter and found some cool things about them and what i can do to make a professional Transmitter module like Radio-Master and Flysky mid to high range ones.while researching i found that all proffesional grade ones support ERLS which is open-source projects so,I can use them in my transmitter module

Finally I have a idea about the working and functionality of my transmitter in pen and paper ...XD...

June 9th : Design the schematic and pcb for ELRS-TX .

I made the schematic and pcb of ELRS-TX in kicad.I also attached the images of all layers of pcb,schematic and 3d view of pcb in the github repo with the gerber files and libraries used in pcb.

Here are some images :

June 10th : Design the pcb and choose parts for ELRS-TX

I first make a list of components which will be used in transmitter module and then make a schematic according to it and then I make a pcb according to it in which the ELRS-TX pcb can be inserted easily so it can be used as plug and play module.
