Board Dimensions

For those interested, the basic board dimensions are shown below, all measurements are in inches and the grid

spacing is 0.1". The SparkFun Cryptographic Co-processor PCB itself, measures (approximately) 1x1 inch.

Additionially, we have provided a PDF of the dimensional drawing, if necessary.

Board dimensions in inches.

Hardware Hookup

Note: To follow this tutorial, an Artemis microcontroller board has to be used with this product due to the

buffer size required for the I C bus.

For more advanced users, other microcontrollers can be used, but the buffer size of Wire library and/or the

syntax for the serial print statements will need to be modified. (*This is outside the scope of this tutorial.)

With the Qwiic connector system, assembling the hardware is fairly simple. For the examples below, all you need

to do is connect your Cryptographic Co-Processor Breakout to a RedBoard Artemis with a Qwiic cable. Otherwise,

you can use the I C pins, if you don't have a Qwiic connector on your microcontroller board. Just be aware of your

input voltage and any logic level shifting you may need to do. (*Don't forget to plug the Artemis into a computer

with a USB-C cable.)

Hardware assembly between the RedBoard Artemis and a Cryptographic Co-Processor Breakout board.

Note, the setup shown here is used for the configuration example and the single-board examples (1,2,3 and 5).

For the more advanced examples that involve Alice and Bob (Example 4 and Example 6), you will need to setup

two Artemis boards - each with their own co-processor. Additional hardware hookup instructions are included at

those sections.
