Hello, I am new to EasyEDA and am trying to create a custom prototype board for the L293D chip. Essentially, I need pads for the chip, some of them pre-wired, like GND and Vcc, but most of them just connecting to adjacent pads, where I can manually solder additional components. Additionally, I want a 5x10 grid that can fit DIP components. I also need letterings (A, B, C, D, 1, 2, 3, 4 etc). What's the easiest way to do this?
