* Header to connect USB-Serial for Arduino bootloader usage

The board is connected to the standard 20-pin target connector used on the ChipWhisperer system. In addition you will require connection of the SMA connector to perform power measurements:

The clock jumpers allow you to connect the HSOUT and HSIN lines to the two XTAL pins on the ATMega328P. Normally you would mount JP8, which routes the HSOUT line from the ChipWhisperer to the "External Clock Input" on the ATMega328P.

Finally, you can also solder a wire from pin 14 (PB0) of the ATMega328P to pin 10 (PB7, the XTAL out pin). This allows you to enable the internal oscillator of the ATMega328P, and also enable the "Clock Out" pin. This clock output drives the internal oscillator frequency onto the output pin, which you then route to the HSIN lines.

The serial header at JP4 provides a method of connecting a standard serial cable to the NOTDuino board. Note the "RST" pin is broken out, allowing you to use a serial cable with a "DTR" pin to control the reset of the ATMega328P (which is required for the Arduino bootloader).

If you wish to use the Arduino software with the NOTDuino board, there is two main methods of doing that:

# Using board entirely stand-alone.

If using the board with the ChipWhisperer-Lite attached (i.e. using the ChipWhisperer-Lite as the capture hardware), this requires the fewest modifications. To use the board you will need to:

</li></ol>

If using the board stand-alone, you will need to perform the following:

<li>Connect a USB-Serial adapter to JP4. You can connect the VCC line of a serial port to the &quot;+3v3&quot; line, as the board can be powered from 5V '''when not connected to the ChipWhisperer-Lite'''. Never connect the board to a 5V line with the ChipWhisperer-Lite attached, as it will ''destroy the ChipWhisperer-Lite''.</li></ol>

The Notduino kit includes all the parts to assemble the Notduino kit. The following shows the kit parts:

There is no specific assembly procedure for the board. The values of components have been marked on the blank PCB, here are some general instructions for the assembly process:

# The test-points (including the &quot;GND&quot;) can be made using a cut-off resistor lead. This gives you something to clip a test point onto.
