Cryptographic Co-Processor ATECC508A (Qwiic) Hookup Guide





Introduction

���� Note: Please follow through the hookup guide in its entirety before using this board. The chip cannot be

re-configured after it is PERMANENTLY locked.

The SparkFun Cryptographic Co-processor Breakout ATECC508A (Qwiic) takes all the great features of the

Microchip ATECC508A Cryptographic Authentication Device and adds two Qwiic ports for plug and play

functionality. In this tutorial we will cover the fundamentals of cryptographic authentication and how to use the

ATECC508A to add a very high level of security to your projects.

The ATECC508A is capable of many cryptographic processes. This tutorial focuses on Elliptic-curve cryptographic

digital signatures (ECC) - using asymetric private/public keys. If those last few words are new to you, please read

on! We will spend some time explaining in a bit.
