Our product applied to home burner, Which simply means, AC 230V foolow the relay ,mcu control realy stwitch.
and lcd show the seting ,and Push button Settings。
firstly. the power scheme is OTG 。 We choice lnk306 , Lowest Component Count, Energy-Efficient Off-Line Switcher IC, and output 12v,this voltage be use of relay power.
Then, we need 7805 or 7803 ,to generate 5v and 3.3v to driver the IC of circuit.

The STM8L-DISCOVERY helps you to discover the STM8L ultralow power features and to
develop and share your applications. It is based on an STM8L152C6T6 and includes an
ST-Link embedded debug tool interface, LCD (24 segments, 4 commons), LEDs and push
buttons.
