I was wondering can you control 4 channel relay with boltiot using python

Hi @hemsharan2050,
Yes, you can use it. The Bolt has 5 digital GPIO pins(pin 0,1,2,3,4), all of which can be used to control 1 channel of the relay. But the Bolt GPIO pins work on 3.3V Voltage levels, so make sure your relay channels support it, if you are not sure just try hooking it up. Do let me know if you need any other help.

Thank you so I will be required to buy the 3.3 volt relay instead of the 5 volt standard delay is that right

@hemsharan2050 that would be recommended, but a 5V relay might work too, there’s a 5V supply pin on the Bolt, but it doesn’t have 5V GPIO Pins. The better option would be a 3.3V relay or a 5V relay that supports 3.3V logic levels(GPIO PINS).

ok thank you and is there a way to boost up the output voltage in the GPIO pins

Hi @hemsharan2050,
For that, you may use a logic-level converter like this one.
