X-CUBE-IKA02A1 Software description
• The X-CUBE-IKA02A1 software package is an expansion
for STM32Cube, associated with the P-NUCLEOIKA02A1 expansion board.
• It is compatible with NUCLEO-F401RE, NUCLEO-
L053R8.
Key features
• Complete middleware to build applications using
electrochemical gas sensors with signal conditioning
done by TSU111.
• Library uses STLM20 temperature sensor for
compensation over temperature range.
• Easy portability across different MCU families, thanks to
STM32Cube.
• Low-power optimization (suitable for the STM32L0 MCU
family).
• Free, user-friendly license terms.
