hi! I read this specs: Microchip® PIC32MX795F512 processor

80 Mhz 32-bit MIPS
512K Flash, 128K RAM
USB 2.0 OTG controller

10/100 Ethernet MAC Dual CAN controllers

But, I can't find dedicated pins our a ethernet jacket in images... How can we use ethernet built-in resource?

Thanks

Look for a thread "Ethernet shield". Freaking Antispam doesn't let me post links. :roll:

but, as the description says "ethernet built-in", I don't wanna use a shield... how use the internal built-in resource of this board?

The MAC is internal but you still need an external PHY...

See an example circuit here: [url]http://ww1.microchip.com/downloads/en/DeviceDoc/61166A.pdf[/url]

alright... this would seem dumb, but: with chipkit max32, where can I solder a rj45 jack? need something more?

thanks :D

You need more than just an RJ-45... You need a PHY, like: [url]http://www.national.com/mpf/DP/DP83848C.html#Overview[/url]

The MCU connects to the PHY with a handful or two of pins (that are on J8 of the Max32, I believe), and the PHY connects to the RJ-45.
