1a. Voltage regulator

2. DS3231 I2C RTC

2a. Battery Holder for DS3231

3. SSD1327 OLED DISPLAY (Pin Headers)

4. 4x Optocoupled Relay Assembly

5. 2x 12v Optocoupled/Transistor powered outputs (500mAh)

6. 2x I2C BME/BMP280 Pressure/Thermometer (1x pin headers + 1x molex or jst connector)

7. 4x Tactile-switch buttons

8. All the passive components required to make everything work togheter

I'm really open to changes or suggestions, and will let you take decisions like which microcontroller pin to use for each input/output.
