LR12A01 FAQ
Q: Ciao! Posso ricevere più informazioni in merito? Non capisco! Nello schema 2 il collegamento viene fatto con i pin "set e reset" in parallelo, ma nelle note c'è scritto che non si devono alimentare i pin "set/reset simultaneamente, quindi o si può (vedi schema 2) o le informazioni sullo schema 2 sono errate, nello schema indipendentemente da quale pulsante si da l'impulso, arriva il segnale negativo su GND, SET e RESET simultaneamente, la domanda è, si può o non si può usare quello schema per fare funzionare il modulo in modalità keep quiescient current = 0? A: Dear friend, 1 When no button is pressed, the power GND is not connected, and the power supply will not have power output, so it is 0UA standby. 2 When the B1 button is pressed, the power GND is connected, and a low-level trigger signal is given to the "RESET" port. At this time, the "SET" port is disconnected. 3 When the B2 button is pressed, the power GND is connected, and a low-level trigger signal is given to the "SET" port. At this time, the "RESET" port is disconnected. Q: Dear friend, in the wiring diagram number 2, so how is, if...
