Assembling the Flash Board

In AVR, Hardware on May 7, 2010 at 00:01

Here is a step-by-step instruction for assembling the Flash Board, starting from these components:

Dsc 1386

The 24M01 1 Mbit EEPROM is already on the board. The build proceeds essentially in flattest-to-higher order, so that when you turn the pcb around for soldering, you can push down the part properly.

We start with the 470 Ω current limiting resistor for the LED:

Dsc 1388

Try to make nice and shiny joints:

Dsc 1387

Cut off the excess wires:

Dsc 1389

Next is the little start button:

Dsc 1390

There are four pins to solder:

Dsc 1391

They are a bit long, so it’s best to cut them off:

Dsc 1393

Next, the LED. This one is polarized, be sure to put it in the right way:

Dsc 1394

The last component on the top is the 2×3-pin ISP header:

Dsc 1396

Again, make sure all pins have good solder joints:

Dsc 1397

Now, all we need to do is solder in the 4 6-pin headers. The easiest way to do so is to push these headers into a JeeNode for proper positioning:

Dsc 1398

The push the Flash Board on top and you’ve got a convenient way to solder them:

Dsc 1399

That’s it, done!

Dsc 1400

Now you can upload the isp_capture.pde sketch on this page and use this brand new ISP programmer.

Happy programming!
