Descriptions:

CW01 - WiFi Core

This xCHIP forms part of the core modules and is equipped with Wi-Fi. The Wi-Fi module offers internet connectivity which allows the user to store data on the cloud which enables remote data access and opens up for the world of IoT.

CS11 - Core with SD Card Interface

This xCHIP is a low-power microcontroller using the 32-bit ARM Cortex -M0+ processor and ranging from 32- to 64-pins with up to 256KB Flash and 32KB of SRAM.

IP01 - USB Programming Interface

This xCHIP is an interface module which is equipped to power and program other modules via a USB A connector. The USB A connection is required for programming the range of CPU Core ☒CHIPS over the USB-serial bridge provided by the FT232R.

OD01 - OLED Display 128x64

This xCHIP forms part of the output modules and is equipped with an OLED display unit that is capable of displaying any graphics or text. Very useful as a sensor data display.

PB04 - Dual AA Intelligent Battery Power Supply

This xCHIP module houses 2 AA batteries to supply power to other connected xCHIPS. The PB04 makes use of the INA199A2 current sensor and MAX11647 Analog to Digital Converter. These two low-cost precision sensors allows for accurately measuring power usage, battery voltage and current draw.

The PB04 features an AAT1217 which is a high efficiency, synchronous, fixed frequency, step-up converter designed for battery-powered applications. The high 1.2 MHz switching frequency and completely integrated control circuitry maintains excellent regulation, ripple, and transient response throughout the full load range.

Light load mode operation and low quiescent current allow the AAT1217 to maintain high efficiency performance for light load conditions. With a 1.2A peak inductor current limit, the AAT1217 is capable of delivering 400mA from dual AA cells batteries.

RL03 - LoRa Radio (915 MHz)

This xCHIP features an SC18IS602B SPI/I2C converter IC for handling radio operations, the on-board RFM95W LoRaTM module provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

SG33 - VOC & ECO2 Sensor

This xCHIP is equipped to sense a variety of Volatile Organic Compounds (VOCs). This xCHIP is based on the CCS811 which is an ultra-low power digital gas sensor which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs), for indoor air quality monitoring, a micro-controller unit (MCU), and an I2C interface.

CCS811 is based on ams 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. 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. CCS811 supports multiple measurement modes that have been optimized for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications.

SI01 - IMU 9DoF

This xCHIP module comprises 3 sensors, an accelerometer that measures movement of the X,Y and Z axes, a magnometer that computes orientation to magnetic north, on the X,Y and Z axes, therefore we can calculate which direction we are facing as well as the angle at which we are leaning. The last sensor is the gyroscope that measures our orientation to the center of the earth.

SL01 - UVA, UVB, Light Sensor

This xCHIP forms part of the sensor modules and is equipped with a light sensor that is capable of measuring the luminosity (Wide Dynamic Range — 3 lux to 220k lux) (visual brightness), UVA and UVB radiation. The light sensor converts solar UV light intensity to digital data and has displayed reliable performance of UV radiation measurement inner long time solar UV exposure.

SN01 - GNSS (GPS) Sensor

This xCHIP is equipped with a NEO-6M GPS receiver. The 50-channel u-blox 6 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. The dedicated acquisition engine, with 2 million correlators, is capable of massive parallel time/frequency space searches, enabling it to find satellites instantly. Innovative design and technology suppresses jamming sources and mitigates multi path effects, giving the NEO-6 GPS receivers excellent navigation performance even in the most challenging environments.

SW01 - Advanced Weather Sensor

This weather sensor xCHIP is equipped with a weather sensor that is capable of measuring the temperature, humidity and atmospheric pressure.

The humidity sensor provides an extremely fast responce time for fast context awareness application and high overall accuracy over a wide temperature range.

The pressure sensor is an absolute barometric pressure sensor with extremely high accuracy and resolution.

The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature.
