AD8232 ECG模块的引脚说明

Pin Name	Description
GND	Power Supply Ground
3.3v	Power Supply 3.3v
Output (ADC)	Operational Amplifier Output. The fully conditioned heart rate signal is present at this output. OUT can be connected to the input of an ADC.
LO-	Leads Off Comparator Output. In dc leads off detection mode, LO? is high when the electrode to ?IN is disconnected, and it is low when connected
LO+	Leads Off Comparator Output. In dc leads off detection mode, LOD+ is high when the +IN electrode is disconnected, and it is low when connected
SDN Pin	Shutdown Control Input. Drive SDN low to enter the low power shutdown mode.
RA (Right Arm)	RED Biomedical electrode pad RA(input). Instrumentation Amplifier Negative Input. ?IN is typically connected to the right arm (RA) electrode
LA (Left Arm)	YELLOW Biomedical electrode pad LA(input). Instrumentation Amplifier Positive Input. +IN is typically connected to the left arm (LA) electrode
RL(Right Leg)	GREEN Biomedical electrode pad RL(input). Right Leg Drive Output. Connect the driven electrode (typically, right leg) to the RLD pin.
3.5mm ECG Biomedical Electrode Connector Jack	Combine Biomedical Electrode pad Connector of RA, LA, RL
