Mbed Ethernet connection

I just received my mbed module. This little ARM device is pretty cool, and the associated tools works quite nice. Of course they cost a lot of money, I received mine for free for the mbed contest. Really kool no ? ;)

After the classic blink test, I decided to go for a network test. But I don’t have any magnetic Ethernet module right now (In fact, I should have one, but I’m unable to find it). So let’s go for a magnetic less ! The doc on the mbed dedicated page say that should be fine. I decided to pull the RJ45 socket from an old broken WRT54.

The main issue is to figure out how to solder this RJ45 on a veroboard. Here comes the fun part, I remembered that radio-amateur use a technique called “dead bug soldering”. Check this guidelines from the NASA for examples.

I decided to give it a try :

Just glue the RJ45 on the veroboard and use a common wrapping technique : Not so bad ;)

The next step is to flash a network example to test.

That’s really fun, the mbed works pretty well. I secretly hopes that somebody will come with a mbed like with opensource hardware and software.

Enjoy wired networks ;)

  1. Very good job. I just wander if you could post the schematic of this proyect in your blog and suggest which is the best way to test the circuit. Thanks.
