I have a project with a Arduino Ethernet Board and PIR Module
I need redesign the board to remove the components that i not use. i only use GND, 5V and 1 digital pin for the PIR MODULE, Ethernet Port and for the LED another digital pin and GND. You can see the photo of my prototype attached .
The idea is reduce the size and cost !!! VERY IMPORTANT
i Want change the power supply and 6-pin serial programming header for a micro usb, both funtion (programming and power in the same usb)
In the photo you can see the PoE module in the Ethernet Board. i donÂ´t use this component is necessary remove it too
If you have another question let me know!
