+ | The default configuration has historically been to use the PullDown config, i.e. when you pull GPIO23 low the heater is on and when you pull GPIO23 high the heater is off. Please keep in mind that you'll have to have some script/code in your setup that makes sure that GPIO23 is pulled high as soon as the system has booted (to be sure the heater is off) or change your setup to PullUp connection instead if you don't want to worry/ | ||
