DINGHOME_HK32F103

Introduction: I made a microphone-type limited doorbell. The doorbell at home is not easy to use (it has been used for 9 years and it can no longer make calls. It has been repaired twice because I don’t want to repair it). I specially made a board that is compatible with the hole position and layout. Some custom features have been added.
