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.

SG33 – VOC and eCO2 xChip (CCS811)

This xChip is a gas sensor module, based on the CCS811 by AMS. The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor that is equipped to sense a wide variety of Volatile Organic Compounds (VOCs) for indoor air quality monitoring with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC), and an I2C interface.

The CCS811 is based on AMS’s unique micro-hotplate technology which enables a highly reliable solution for gas sensors, very fast cycle times and a significant reduction in average power consumption.

The integrated MCU manages the sensor drive modes and raw sensor data measured while detecting VOCs. The I2C digital interface significantly simplifies the hardware and software design, enabling a faster time to market.

The CCS811 supports intelligent algorithms to process raw sensor measurements to output a TVOC value or equivalent CO2 (eCO2) levels, where the main cause of VOCs is from humans.

The CCS811 supports multiple measurement modes that have been optimised for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications.
