P-NUCLEO-IKA02A1 STM32 Nucleo pack: electrochemical toxic gas sensor expansion board with CO sensor Data brief Description The P-NUCLEO-IKA02A1 evaluation pack provides a reference design for various electrochemical sensors. The STM32 Nucleo gas expansion board interfaces electrochemical sensors with the MCU on the STM32 Nucleo development board. Two TSU111 operational amplifiers provide signal conditioning they are ideal for electrochemical sensing thanks to their high precision and low power consumption. The expansion board includes an ultra-low current precision analog temperature sensor STLM20 used for compensation of gas readings. STM32 Nucleo boards provide an affordable and Features flexible way for users to experiment with new ideas and build prototypes with any STM32 STM32 Nucleo gas expansion board microcontroller line. The NUCLEO-L053R8 is compatible with most electrochemical designed for low power applications. sensors four different footprints for sensors The design and componentry are optimised for (PCD13,5, PCD17, Mini and TGS5141) battery operation and maximum battery life time. two-, three- and four-electrode sensors signal conditioning with TSU111 STLM20 temperature sensor changeable gain NUCLEO-L053R8 Ultra-low-power ARM Cortex -M0+ MCU (32 MHz max.) with 64 Kbytes Flash and 8 Kbytes of SRAM Carbon monoxide sensor Figaro TGS5141 coin-cell sensor expected life time > 10 yrs can pass 5000 ppm EN50291 Low power design for long battery life RoHS compliant June 2017 DocID030604 Rev 1 1/6 www.st.com For further information contact your local STMicroelectronics sales office Board description P-NUCLEO-IKA02A1 1 Board description STM32 Nucleo gas expansion board consist of three main blocks gas sensor footprints attached carbon monoxide sensor TGS5141 operational amplifiers TSU111 for signal conditioning precision analog temperature sensor STLM20 for temperature compensation Information regarding the NUCLEO-L053R8 and NUCLEO-F401RE development boards can be found at
