What is it?

AT89S Standalone Programmer for programming the older AT89S devices without a computer. Almost all of the devices in the device list are still in production at Microchip. The programmer operates the same as my LP Programmer here.

Easy to use, just load the files and set up the configuration, the programmer then runs as a standalone programmer. Great for bulk programming or for updating devices for customers. I had a few inquiries regarding a programmer for these older S51 devices so I thought I would bring this item back for sale. There are only a few of these boards left. Once they are gone, this item will be retired.

Why did you make it?

Back in 2008, I needed a way to program a solar-powered sensing device on my property 350' away from any power source. I did not want to bring my expensive laptop outside every time, nor did I want to bring all the cables, power supply, etc. So I developed the first version, and from there were 4 more versions this one being the latest with support for more devices.

What makes it special?

You do need a computer to set it up initially. Once set up, it runs from the target power and will program as many devices as you want. The data is stored in the programmers memory until it is erased. I have used this programmer a thousand times because of its' simplicity and reliability.
