I'm trying to make Arduino Single-Sided Serial Board (version 3) for my school project. But after I printed the given artwork "A4 Image for Toner Transfer (.png)" I could see the foot print of the Atmega328 is not match with the given image drill holes. So what should I do now.
I must be thankful to you if you will kindly give me the correct artwork which can directly print and make the pcb.
Perhaps you need to print the file from a program that will let you specify the printing scale, particularly if you are printing on US Letter paper (shorter than A4). I just printed it using Preview (on a Mac) and specifying 100% scale. The pin spacing printed out at 1/10th Inch, exactly as expected.
