Hello,
I have purchased a 2 Channel SPDT Relay (<LINK_TEXT text=“https://www.seeedstudio.com/Grove-2-Cha … Relay.html”>https://www.seeedstudio.com/Grove-2-Channel-SPDT-Relay.html</LINK_TEXT>) as it was marked as compatible with Raspberry Pi. But it looks that input signal should be 5V to drive the relay, while Raspberry Pi GPIOs only provide 3.3V.
Will it work anyway or should I use another reference ? If so, which reference would you recommand ?
Best Regards
Thierry
Hello
I have powered the Relay board with 5V from the Raspberry, while driving SIG1 and SIG2 from 3.3V GPIOs of the Raspberry.
It looks to work fine for the time being …
Do you have any comment on this ? Can I stay with this setup or should I use another Relay board ?
Best Regards
Thierry
