MINI-M0 for STM32 is a small ARM® Cortex™-M0 development board containing STM32F051R8 microcontroller. It perfectly fits into standard DIP40 socket. Board is equipped with 16MHz SMD crystal oscillator, and 32.768KHz crystal which can be used for internal RTCC module. It has reset button and three signal LEDs.
Board comes preprogrammed with fast USB-UART bootloader, so no external programmers are needed for development. It operates on 3.3V power supply. On-board voltage regulator allows the board to be powered directly from USB cable.
Ozone 2 click is an Ozone detection (O3) sensor, based on the MQ131 gas sensor. This gas sensor has a sensitive layer made of SnO2, which changes its resistance when exposed to ozone. The sensor is able to sense O3 concentration in the range of 10 ppm to 1000 ppm. The Click board™ is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ131 sensor. Low cross-influence of other oxidation gases such as CL2 and NO2, ensures a good accuracy of the sensor. The analog output of the sensor is sampled by a high-resolution 22-bit A/D converter (ADC), which offers the conversion result on the SPI interface. The analog signal from the sensor is also available, allowing an external ADC to be used.
USB UART 2 click provides USB isolation and carries the ADUM4160BRWZ USB port isolator.
The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over UART interface, with additional functionality provided the following pins on the mikroBUS™ line: RST, CS, PWM, INT.
Temp&Hum 10 Click is a smart temperature and humidity sensing Click board™, aimed towards IoT applications, due to its extremely small size and very low power consumption. It can measure a wide range of temperature and relative humidity (RH) values with high accuracy. The sensor used on this Click board™ offers the complete measurement system: capacitive RH sensor, thermal sensor, analog and digital data processing, and the I2C communication interface. Featuring a good reliability over time, high accuracy, and low hysteresis, it is an ideal solution to be used in various temperature and humidity related IoT applications.
Temp&Hum 10 click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
