Revisiting the DSETA board with an AT89C51ED2

Hi all!

I’m very busy last months working on new boards and projects, sorry for the delay!

Some months ago I review the DSETA board due the obsolescence of the microcontroller. I use this board in some projects succesfully. But when I try to manufacture a batch of this boards, I found that the microcontroller (AT89C51RE2) was obsolete. So, the board needs an update to change the microcontroller and maintain most of the features that it has. Now that Microchip buys Atmel, obsolescence and samples will not be a problem.

To replace the RE2 microcontroller, I choose one very similar, the AT89C51ED2 microcontroller. Mainly because it shares most of features with the old one and footprint and pinout is almost the same, so replacement is relatively easy to do.

Come in and you can see the new board features, changes and more!!
