Kitronik Air Quality Control HAT for Raspberry Pi

Monitor, log, and react to gathered sensory data and then store and display data effectively with the Pi filesystem and an onboard OLED screen.
Add external devices, such as analogue sensors, servos, motors, and heater pads that allow for additional monitoring and reading-based actions.
Conforms to Raspberry Pi standard for HATs.
The HAT is powered via the Raspberry Pi GPIO connector.
High-Power Output: GPIO13 & GPIO19 (1A current draw max).
Servo Output Control, GPIO6 (Supply Voltage) and Piezo Buzzer Control, GPIO26.
Analogue Inputs (RP2040 ADC): ADC0, ADC1 & ADC2 (Each with 3.3V & GND).
ZIP LEDs: 3 onboard (controlled via RP2040)
Additional Pin Breakouts: GPIO22, GPIO23, GPIO24 + 3.3V & GND.
BME688 & OLED Display Control: I2C Bus (GPIO2 & GPIO3).
README information and example programs are available on the Kitronik GitHub repo.
This HAT is compatible with all Raspberry Pi versions that feature the 40-pin GPIO connector. (Pi 2, 3, 4, 5, Zero and Zero 2). It has been tested with Pi 2, 3, 4, 5 and Zero 2.
