Power

There is a power status LED to help make sure that your Cryptographic Co-processor Breakout is getting power.

You can power the board either through the polarized Qwiic connector system or the breakout pins (3.3V and

GND) provided. This Qwiic system is meant to use 3.3V, be sure that you are NOT using another voltage when

using the Qwiic system.

Power connections.

LED

The board includes a red power LED to indicate you have power plugged in properly. Note, there is a jumper on

the back to disconnect this from the circuit. This is useful if you really want to conserve current consumption on

your system.

ATECC508A Cryptographic Co-Processor

The co-processor on this board is the Microchip ATECC508A. It's primary features include creating/storing ECC

keys, creating digital signatures and verifying them. It is also capable of doing many other cryptographic processes

includeing SHA-256 hash, Diffie-Hellman Key Exchange, and high quality random number generation. For more

details on the ATECC508A cryptographic chip, check out the datasheet.
