BR01 - Raspberry Pi Bridge
This xCHIP is designed to interface with all Raspberry Pi modules. This provides an interface to support the xCHIP ecosystem, adding support for many additional sensors, etc.
- 1 X xBUS connection to interface with xCHIPS
OC03 - Relay Out
OC03 is a low-voltage control relay module able to switch AC and DC loads.
The optically isolated relay is controlled by a PCA9554A IO expander, which provides an control interface to the switch. The PCA9554A has several selectable I2C addresses accessible via solder pads.
The TLP241A photorelay consist of a photo MOSFET optically coupled to an infrared light emitting diode which switches a AC or DC load. It provides an isolation voltage of 5000 Vrms, making it suitable for applications that require reinforced circuit insulation.
- Low Voltage AC/DC Control Relay
- Load Voltage Range: 0 - 40 V
- Load Current Rating: 2 A
SG33 - VOC & eCO2 Sensor
This xCHIP is equipped to sense a variety of Volatile Organic Compounds (VOCs). This ☒CHIP 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.

SW01 - Advanced Weather Sensor
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.
- Measures temperature (°C)
- Measures atmospheric pressure (Pa) /altitude (m)
- Measures relative humidity (%)
SL06 - Gesture Sensor
This xCHIP features advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS) and Color Sense (RGBC).
- I2C data rates up to 400 kHz
SH01 - Capacitive Touch
This xCHIP is based on the CAP1296 which is a multiple channel capacitive touch sensor controller. Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. In addition, the CAP1296 can be configured to detect proximity on one or more channels with an optional signal guard to reduce noise sensitivity. The CAP1296 includes Multiple Pattern Touch recognition that allows the user to select a specific set of buttons to be touched simultaneously. If this pattern is detected, a status bit is set and an interrupt is generated.
- Six 4 Capacitive Touch Sensor Inputs
- Proximity Detection
XC10 - 10-Pack xBUS Connectors
The xBUS is the main connection between the xCHIPs. Most xCHIPs will have a connection on all 4 sides, but some will have a connection sacrifices either for space or for other connectors, such as USB or antenna connectors.
Raspberry Pi is not included in the xKIT.
