SKAARDUINO POE BOM

hello everyone,

i'm currently trying to build a SKAARDUINO board, thanks to kasper , and the exellent (team) work.

I got my board done from the EAGLE file, and now it's time to solder all the components, my problem is where to get some of them.

For exemple the HY931147C RJ45 , i can't find it on MOUSER, RS or FARNELL.

Did someone from the european side of the world , did order the same BOM and is willing to share is source.

 

When you get the ATMEGA on the board, do you have to set the fuse before burning the bootloader ?

 

many thanks

I tried to update the github

I tried to update the github repo just now, but had some issues. Wanted to include the BOM and also assembly guidelines I have used. I can send it to you if you send me an email, just write to kasper@ and then our domain.

 

The HY931147C is the kind of component I couldn't find in official channels myself, so alibaba will help you :-)

bootloader

hello,

i've just finished the soldering, the board is running so far (i'm still waiting for the RJ45)

I burned the skaarduino bootloader with a usbasp, upload my firt sketch, (blink ) running OK, but when i want to upload again, it looks like the bootloader is gone ???

So i have to burn it again, any ideas ?

thanks

wiznet not working

hello,

i don't know if anyone else tried to make his own skaarduino board, i did , but i got some problems with the ethernet part.

The SPI does not seem to communicate with the wiznet 5500, if i try a simple sketch like "chat server" , it tells me my IP is 255.255.255.255

Do i have to use ethernet2 librarie ?

I plug a logic analyser on MISO,MOSI,SCK and SS, and MISO and SS are blank.

If i make a sketch with a blink on those pins , i can see them blinking, strange, like if something was wrong in the spi librairie , not mapping the right pin ?

BTW, i did install the skaarduino hardware file.

 

I hope someone can help me with this.

best regards
