information on the Nano board. The spreadsheet for the connectors will give an idea of what is needed for connections to the board from the front panel along with connections to the Nano.
There will be a LM7805 regulator (5V) on the board which should be mounted near the edge of the board with metal tab on outer side of board. The regulator should have a 100uF capacitor on the input, and a 1uF capacitor on the output. The 5V output of the regulator will feed the 5V input of the Nano. There will be a 2-pin connector for the +12V input with +12V on pin 1. There will also be a Ground connection. There will also be a 2-pin connector that will go between the +12V input and the input to the LM7805 which will connect to a power switch. These should be located near the 7805 regulator. These connectors, as well as the 7805, will be located on the lower edge of the board as indicated (they are being moved from the right side where they were previously located).
The 30K and [url removed, login to view] will form a voltage divider with the top leg of the 30K resistor connected to a wire pad that will be used as a sense input. The center of the resistor divider will connect to A0 on the Nano chip. The other leg of the [url removed, login to view] resistor will be connected to Ground.
There will also be a Current Sensor module on the board which will be connected using a 3 pin connector. The module will be mounted such that pin 1 (Left) will connect to Ground, pin 2 will connect to A1 of the Nano, and pin 3 will connect to 5V.
There will be two 470 ohm resistors on the board that will be connected between outputs of the Nano, and the connector to the two LED's. The center pin of this connector will be Ground.
The connections to the meter must be to pins A4 and A5 on the Nano as indicated. These pins cannot be changed on either the Nano or the connector as they are defined by the Arduino library.
If the ordering of any Digital pins from the Nano need to be changed to facilitate routing, then check with us. This may be possible as long as they remain grouped by function on the Nano chip. Note also that pin designations on the connectors must remain as indicated.
Pin D12 from the Nano will connect to the Gates of the 4 MOSFET's. They will each connect via an individual 1K resistor. The MOSFET's should be mounted near the edge of the board with the mounting tabs outwards. The SOURCE pins will connect together, and will have a wire hole capable of accepting 14 gauge wire. The etch must be capable of carrying 25 Amps. Also, the DRAIN pins will connect together and have a wire pad capable of accepting 14 gauge wire. This Ground connection will also be the board Ground.
The 3, 4, and 5 pin connectors should be located upper-right and right, as indicated in the attachment. Note that there will be two of each of these connectors. They will all connect together, but we will only be using one at a time depending on orientation of the board.
I have included the board layout to go by, as well as spreadsheets for reference purposes.
Let me know if there are any questions.

I am a Mechatronics/Electromechanical Engineer. At this time I am preparing a Masters in Automatic control. as I was a student I used to build my own circuits as well as connecting them with microcontrollers.
I know i can make it but i still don't understand what you want to do here. Do you want me to draw the sketch? To make it? Please contact so that i can know if i can take this.
