+To save money, 2 levels are ordered as one board. After manufacturing, the boards need to be divided into 2 parts - upper and lower.<br><br>
+Some components can be replaced with similar ones (for example use a fuse with terminal contacts). Some SMD components (for example optocouplers) can be replaced with similar SOT components.<br>Most of the components can be purchased inexpensively on Aliexpress, the rest in your local stores.<br><br>
+The outdoor temperature sensor must be connected to the **TEMP1** connector, the indoor temperature sensor must be connected to the **TEMP2** connector. The power supply for the sensors must be connected to the **3.3V** connector, GND to **GND**.<br>
+**The opentherm connection polarity does not matter.**
 <!-- **Important!** On this board opentherm IN pin = 5, OUT pin = 4 -->
