The group at U of Minnesota that designed the board created a final report describing the design.  It is available
 +
[http://www.cas.mcmaster.ca/~lawford/Pacemaker/PacemakerHardwareOverview.pdf here.]

Here are some photos of the prototype hardware reference platform that we have produced.

[[Image:PacemakerTop.png]]
 +
 +
The side photo show the standard 2mm power jack.  A 9-12V adapter providing 300mA should suffice.  You can even run the board off of a 9V battery for some time
 +
.

The next photo shows the BNC and binding post connectors that we have put on so allow the boards to be easily connected to a PC running Labview or some other software to simulate a heart and facilitate testing and debugging.

Line 9: Line 27:
We will be releasing the Bill Of Materials (BOM) and the schematics for the hardware once the design is finalized so that you can also produce your own boards if you would prefer to do that.

Pacemaker Hardware Reference Platform Details

The group at U of Minnesota that designed the board created a final report describing the design. It is available here.

Introduction

Here are some photos of the prototype hardware reference platform that we have produced.

The side photo show the standard 2mm power jack. A 9-12V adapter providing 300mA should suffice. You can even run the board off of a 9V battery for some time .

The next photo shows the BNC and binding post connectors that we have put on so allow the boards to be easily connected to a PC running Labview or some other software to simulate a heart and facilitate testing and debugging.

Here is the originial design of the Pacemaker Hardware Reference Platform.


Bill Of Materials (BOM)

We will be releasing the Bill Of Materials (BOM) and the schematics for the hardware once the design is finalized so that you can also produce your own boards if you would prefer to do that.
