Summary
The article describes redesigning the EasyDownloader V1.1, a Flash Writer for AT89C2051/4051 microcontrollers, originally designed with a double-sided PCB. The author created a more accessible single-sided PCB version, easily made by hand using permanent ink pens and simple design tools like Paint. The layout and component placement are straightforward, intended for easy DIY production. A critical note is to connect jumper wires from pins 12-19 on the microcontroller to the corresponding pins on the ZIF socket on the PCB's underside.Parts used in the EasyDownloader V1.1:
- AT89C2051 microcontroller
- ZIF socket
- Single-sided PCB
- Jumper wires (for pins 12-19 connections)
- Permanent ink pen (for PCB design)
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
