Bootstrapping a Custom Board with Same Processor as NetDuino

Guys

I love the NetDuino 3 Wifi but as a dev kit it has way more space used than i want.

I was thinking about taking the circuit design (same chipset, micro) and building my own board but only keeping the USB, WIFI, 2 COMM PORTS, 1 MISO port, and a few DIO's in the new board.  The idea is to make it  1" x 1" x .5" in layout wih some low profile headers.

If i buy the parts hook em up correctly ... big if lol.

how do i make the micro processor know its a NetDuino 3 WIFI board?

thanks in advance

I think you could just upload the N3WiFi firmware to it, and it should work.

By the way, you could make it super, duper small if you chose to get the MCU in a WLCSP (Wafer Level Chip Scale) package. That's a chip form factor that basically does away with the plastic around the die (the actual silicon wafer) and just puts a thin layer of plastic on top and some solder balls on the bottom. I think that MCU in the N3WiFi is like a 1/4" square in the WLCSP.

Could be pretty cool. And _very_ small.

Though it's worth pointing out; if you want the same wifi as what's on the N3W, it's pretty big.
