ZMOD4450 Evaluation Kit User Manual Description Features The ZMOD4450 Evaluation Kit (EVK) is designed for evaluating User-friendly EVK expedites configuration and evaluation of IDTs ZMOD4450 Gas Sensor Module for Refrigeration Air Quality the ZMOD4450 Refrigeration Air Quality Sensor (RAQ). In addition, a light sensor indicates if the refrigerator door Operates with IDT provided software either with executable is open and a control signal may trigger an external device (e.g., ZMOD4450 GUI or alternatively with firmware programming active filter ventilation, ozone generation etc.) based on the air examples for Windows and Linux quality change. The modular design of the EVK allows simple connection of IDTs ZMOD4450 Evaluation Software allows Windows -based Sensor Boards for different gas sensor derivatives and easy operating systems to communicate with the ZMOD4450 EVK via a integration with other sensor products via the I2C interface USB connection on the users computer, which functions as a The required ZMOD4450 Evaluation Software is available for master. The software and additional related documentation is download on the IDT website, which also provides back- available on the IDT website. ground information on refrigeration gas sensing and sensor programming. The EVKs Communication Board (HiCom) handles the interface between the users computer and the ZMOD4450 module mounted Additional pins provided to measure power consumption, on the ZMOD4450 Sensor Board (Daughter Board). Note: Only one supply voltage, and the GPIO trigger for an external device Communication Board with one Sensor Board can be connected to Integrated light sensor to indicate the position of the the computer at a time. refrigerator door for infiltrated air quality changes The ZMOD4450 Evaluation Kit uses an FTDI controller on the The bill of materials (BOM) and schematics for the Communication Board to handle the USB protocol, translate ZMOD4450 Communication Board and Sensor Board are communications, and synchronize communications with the I2C included in this document interface. The Sensor Board includes a decoupling capacitor. The Communication Board has devices mounted on both sides. The components on the top side generate a stable supply voltage. ZMOD4450-EVK Contents A potentiometer can be used to adjust the internal supply voltage HiCom Communication Board in the typical range from 1.7V to 3.6V. Alternatively, the users external supply voltage can be used. The intensity of the adjacent Sensor Board with ZMOD4450 Gas Sensor Module LED is proportional to the supply voltage. 3.0m Type-B USB to Micro-USB Cable (flat type) ZMOD4450 Evaluation Kit ZMOD4450 HiCom Communication Board Sensor Board USB Cable to Computer ZMOD4450 2018 Integrated Device Technology, Inc. 1 December 20, 2018 ZMOD4450 Evaluation Kit User Manual Important Notes Disclaimer Integrated Device Technology, Inc. and its affiliated companies (herein referred to as IDT) shall not be liable for any damages arising out of defects resulting from (i) delivered hardware or software (ii) non-observance of instructions contained in this manual and in any other documentation provided to the user, or (iii) misuse, abuse, use under abnormal conditions, or alteration by anyone other than IDT.
