What is it?

A used board from an old 10 digits display with 10 seven segment indicators which are controlled via at89c2051. There are 5 connections on the board, one vcc other ground and 3 go to GPIO pions of at89c2051.

To make it work:

You can do a reverse engineering to find out which signal is sent to at89c2051 and display numbers on the seven segment indicators,
Or you can try to reprogram the at89c2051 microcontroller,
Or you can desolder the at89c2051 microcontroller, solder pinheaders and drive the display with your Arduino board,
In the worst case, you can desolder the indicators and use them separately :)

What you get:

A board with ten seven segment indicators for your projects.
All the boards have 10 indicators and at89c2051 microcontroller.
Some boards have smd capacitors other boards have thd capacitors and parts, but they all work the same way.

I ship a random board when you order. The price is for a single board.
