The US082-ZMOD4450EVZ board enables quick
prototyping of the ZMOD4450 gas sensor module for
refrigeration air quality (RAQ) in a custom system
design. The board provides a standard Pmod™ Type
6A (Extended I2C) connection for the on-board sensor
to plug into any desired MCU evaluation kit with a
matching connector.
The US082-ZMOD4450EVZ features Pmod
connectors on both sides of the board to allow
additional Type 6/6A boards to be connected in a
daisy-chained solution with multiple sensors on the
same MCU Pmod connector. Because of the standard
connector and software support, the
US082-ZMOD4450EVZ is the best choice to rapidly
create an IoT system with the Renesas
Quick-Connect IoT.
Features
▪Gas sensor module for RAQ ZMOD4450 sensor
sample mounted:
• Measures gases associated with food ripening
and storage: volatile organic compounds
(including ethylene), amines, volatile sulfur
compounds
• Provides configurable methods of operation
based on application and use case
▪Standardized Type 6A Pmod connector supports
I2C Extended interface
▪Dual connectors allow pass-through signals for
daisy-chained solutions

1. Functional Description
The US082-ZMOD4450EVZ functions as a sensor building block to create a custom system solution. It can be
used individually or with a combination of other sensors using the Pmod Type 6A interface. For more information
on creating your full system design, further information on software development, and additional hardware
availability, see Renesas Quick-Connect IoT.

2. Setup
2.1 Required or Recommended User Equipment
The following additional lab equipment (sold separately) is required for using the board:
▪Any MCU board that supports Type 6A Pmod.
▪US082-INTERPEVZ interposer board if using one of the Renesas MCU kits shown in Table 1.
2.2 Software Installation and Usage
See the Renesas website for the latest version of the e2 studio installer. The minimum FSP version supporting
sensor blocks is FSP 3.1.0. For the latest sensor support, ensure you are using the latest release.
Visit Renesas Quick-Connect IoT for more information about creating your customized system solution.
2.3 Kit Hardware Connections
Follow these procedures to set up the kit as shown on Figure 3.
1. Ensure the MCU evaluation kit has a Pmod connector set to Type 6A (see the kit hardware manual if unsure).
a. If no Type 6A Pmod is available, ensure the MCU evaluation kit can use the US082-INTERPEVZ interposer
board and insert the board into the MCU connector before adding any sensor boards.
2. Plug in the US082-ZMOD4450EVZ to the Type 6A connector, being careful to align Pin 1 on the sensor board
and MCU kit.
3. Connect the J4 and J5 jumpers to place 4.7k pull-up resistors on the I2C bus lines.
a. Only one set of I2C pull-up resistors should be used on the bus. If multiple sensor boards are used, only
one board should have the jumpers present.
b. MCU kits typically do not have pull-up resistors present on the bus lines but double check for them.
4. The INT pin of the ZMOD4450 is a push-pull output signaling if a measurement is being taken. Connect it to
the Busy (GPIO) pin of the Pmod connector by placing Jumper J6 on Pins 1-2. Connect it to the INT pin of the
Pmod connector by placing Jumper J6 on Pins 2-3. Connect Jumper J3 to add an optional 4.7k pull-up resistor
to this line.

US082-INTERPEVZ
