Product Details

xChip Boards

xChips are a rapid electronics development ecosystem to help reduce development time and simplify making custom products as well as aiding learning. Without soldering, wiring, breadboarding, or hardware knowledge you can assemble a circuit in minutes, and concentrate on coding.

xChips are compatible with the platform you want to use and bridges are available for the most popular pltatforms; Raspberry Pi, Minnowboard, Beaglebone, Micro:bit, Pixhawk and 96 boards. Rather than bridging to Ardunio, we offer compatible cores for Arduino Uno, the CC01, and for Arduino Zero, the CC03.

xChips utilise I2C, and due to this bus architecture, unlimited expansion of circuits is possible. Limitations of I2C addresses have been negated by development multiplexers.

Because of its simple connection method, it is easy to build quickly - for prototyping and small product runs

xChips connect to each other using an xBus connector, available from RS 174-4977.

Some xChips need an xPDI connector (RS 174-4974) to connect to programming interfaces, such as the IP02 or IP03.

AH01 – SHA-256 Hardware Encryption (ATECC508A/ATECC508)

This xChip is a core encryption module which forms part of the Crypto module range, running a security algorithm based on SHA-256.This xChip includes the ATECC508A from Atmel, which is a secure CryptoAuthentication device. It is equipped with an EEPROM array that can be used for storing of up to 16 key, certificates, consumption logging, security configurations and other types of secure data. Access to the various sections of memory can be restricted in several different ways and then the configuration can be locked permanently, to prevent changes.The ATECC508A features a wide array of defense mechanisms specifically designed to prevent physical attacks on the device itself, or logical attacks on the data transmitted between the device and the system. Hardware restrictions on the ways in which keys are used or generated provide further defense against certain styles of attack.Access to the device is made through a standard I²C interface at speeds of up to 1 Mb/s.
