Internet of Things Core Kit – XK52
AH01 – SHA-256 Hardware Encryption
This ☒CHIP forms part of the Crypto module range, running a security algorithm based on SHA-256. The ATECC508A from Atmel includes an EEPROM array which can be used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations. Access to the various sections of memory can be restricted in a variety of ways and then the configuration can be locked to prevent changes.

AI01 – I2C MultiPlexer
This ☒CHIP is an octal bidirectional translating switch controlled by the I2C-bus.
BR01 – Raspberry Pi Bridge – This ☒CHIP is designed to interface with all Raspberry Pi modules. This provides an interface to support the ☒CHIP ecosystem, adding support for many additional sensors etc.
CW01 – WiFi Core (ESP8266) – This ☒CHIP forms part of the core modules and is equipped with Wi-Fi. The ESP8266 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.
CW02 – Wi-Fi & Bluetooth Core (ESP32) – An ☒CHIP core Wi-Fi & Bluetooth module. CW02 is based on the ESP32 which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low-power 40 nm technology and an Xtensa® Dual-core 32-bit LX6 microprocessor.
IP01 – USB Programming Interface – This ☒CHIP 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.
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 TLP240A 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.
OD01 – OLED Display 128×64 – This ☒CHIP 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.
PL01 – 3.7v LiPo Battery Power Supply – This ☒CHIP charges a 3.7v LiPo battery via power input from a Micro USB power source. Unless connected to this Micro USB power source, the circuit draws power from the LiPo battery and supply the ☒BUS with power.
SH01 – Capacitive Touch – This ☒CHIP 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 re-calibrated to compensate for gradual environmental changes.
SL06 – Gesture Sensor -This ☒CHIP features advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS) and Color Sense (RGBC).
SU02 – Universal Digital Input – This ☒CHIP is a low-power, monolithic, 8-bit, analog-to-digital converter (ADC).
SW02 – VOC and Weather Sensor – This ☒CHIP is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles.
