Ozone 2 click - Digi-Key

PID: MIKROE-2767 Ozone 2 click carries an MQ131 sensor for Ozone (O3). The sensor outputs an analog voltage, which is converted by the onboard MCP3551 22-bit ADC converter or it is sent to the microcontroller via AN pin on the mikroBUS™, depending on the position of ADC SEL. jumper. The click is designed to run on 5V power supply. It communicates with the target microcontroller over SPI ...
