Hi guys, I need to design a rogowski coil on a 2 layer PCB.

Pending display options, your outline file may need to be inverted in Mods to produce solid white vias surrounded by a black board.
Remember the Roland SRM-20 End Mill, similar to the Roland Vinyl Cutter in the EECS lab, mills off set from black to white.This can be circumvented by lying to Mods and entering a tool diameter of zero. Avoid placing board outline along the edge of your export file, because mods will reject milling edge lines due to clearance limitations.PNG files with resolution greater than 1000 dpi if milling diagonal traces smaller than 12 mils. For motor diode protection, the diode must be placed in parallel with the load and orientated in the opposite direction of current flow.I used N-type MOSFETs which are placed downstream of a load with the drain wired to the load, source wired to ground, and gate wired to a MCU pin in my case. Know your MOSFIT (P-type verse N-type).In your design program, set design rules for trace and pad spacing based on end mill sizing (e.g., if milling traces with a 1/64 in end mill, set spacing to 16 mils).The bottom image is a 3D rendering of my board. The lower right image shows a 2D depiction of my board with additional component information and is hyperlinked to the CAD file. I used 20 mil width traces throughout the 12 V supply region of my board and used 10 mil traces everywhere else. On the right side is your part-library, select the components you want in your circuit and drag&drop them into the breadboard window. Go to breadboard view by clicking on the breadboard tab on the top of the window. As will be discussed in detail below, the incorporation of vias proved difficult with a number of lessons learned. Step 2: Designing in Fritzing Start Fritzing and start a new sketch. This radius calculation assumes perfect positioning of the PCB in the rotating shaft center, which is difficult to achieve. To simplify trace routing I opted to create a board with the bottom layer set to ground with connections to ground made through vias. Hence, the final coil rotation radius was calculated using the design values and the measured shrinking of the PCB.
To provide opportunities to expand use of the PCB, I added resistors and a connector to jump out unused pins of the MCUs (outlined in green below). I also added an area to incorporate an additional power source (e.g., 12V) and set of N-type MOSFETs to power electromagnet coils to drive an induction machine (outlined in orange below). Adding to the base design, I incorporated a circuit containing a button and LED that can be controlled via the MCU per the week's assignment (outlined in blue below). My PCB design is based on Neil’s .5V.1 board which utilizes a ATSAMD11C microcontroller.
