Application circuit of CSJ-R05A and microcontroller

Relevant key device information applied in this article: CSJ-R05A As shown in the figure, it is the application circuit of CSJ-R05A and the microcontroller. Since the microcontroller has a certain amount of electromagnetic interference on the wireless receiving system, this interference may cause the receiving distance of the receiver to become shorter, or may cause the receiver to not work properly. In order to suppress the interference of the microcontroller system to the receiver, a decoupling circuit composed of three color ring inductors and four capacitors is added to the receiver. If necessary, shielding measures can be used on the microcontroller to further suppress interference.
