STM32 Nucleo Multifunctional Expansion Board For Gas Sensors

Product Information

The Gas Sensing Expansion Board for electrochemical sensors
(P-NUCLEO-IKA02A1) is a multifunctional expansion board designed
for use with STM32 Nucleo boards. It features various key
components, including:

TSU111: A nanopower operational amplifier with a low current
consumption of 900 nA and high accuracy of 150 uV.
STLM20: An ultra-low current precision analog temperature
sensor operating at 2.4 V.
Gas Sensor: The board supports four different footprints for
electrochemical gas sensors, including PCD 13.5 mm, PCD 17 mm,
miniature, and TGS5141.

Product Usage Instructions

To use the Gas Sensing Expansion Board (P-NUCLEO-IKA02A1),
follow the steps below:

Ensure you have the necessary hardware and software
prerequisites:

Hardware Prerequisites:
- 1x P-NUCLEO-IKA02A1
- Windows 10 Laptop/PC
- 1x USB type A to mini-B USB cable
Software Prerequisites:
- STSW-LINK009: ST-LINK/V2-1 USB driver
- X-CUBE-IKA02A1 software package

Download and unpack the X-CUBE-IKA02A1 software package from
the provided source.

Connect the P-NUCLEO-IKA02A1 board to your Nucleo board using
the appropriate connectors (ST morpho connector or Arduino UNO R3
connector).

Flash and run the desired project from the X-CUBE-IKA02A1
software package, such as the “Gas concentration reading” example
or the “DataLogCustomLite” example.

Refer to the user manuals UM1955 and UM2230 for detailed
instructions on getting started with the multifunctional expansion
board and the X-CUBE-IKA02A1 software.
