Summary of MakeYour Own Single-Side PCB for Easy-Downloader V1.1 using AT89C2051
The article describes a simplified single-sided PCB design for the EasyDownloader V1.1, a Flash Writer for the AT89C2051/4051 microcontrollers originally designed with a double-sided PCB. The author redesigned it to be easier for personal fabrication, using hand-drawn layouts and a paint program for component placement. Users must connect jumper wires between specific pins on the microcontroller and ZIF socket. The design aims to make building the programmer accessible and straightforward for hobbyists.
Parts used in the EasyDownloader V1.1:
- AT89C2051 microcontroller
- ZIF socket
- PCB (single-sided)
- Jumper wires (connecting pin12-19 of microcontroller to pin12-19 of ZIF socket)
- Permanent ink pen (for PCB etching)
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 however, thus provides a PCB layout and components placementwritten by Paint Program. So simple, but it works fine. Everyone can makeit easily. If you’ve got problem or any suggestion, please sendit to my e-mail address shown above.
Don’t forget, you must connect jumper wires on a bottom of PCB: pin12-19 of the writer(89c2051) to pin 12-19 of the ZIF Socket, respectively
