MakeYour Own Single-Side PCB for Easy-Downloader V1.1 using AT89C2051

The EasyDownloader V 1.1 , a Flash Writer for 89C2051/4051 which was designedby Wichit Sirichote, used  a Double-SidePCB. I think, it’s difficult to make my ownPCB by myself. So that I decided to design a Single-SidePCB instead. My first prototype board wasmade using hand-writing with a permanent ink pen( see later in Figure 3).This page
