More and more semiconductors are produced in packages (the chip's case) which have become impossible to hand solder with a solder iron. The switch from through-hole (THT) to surface mount technology (SMT) has actually made hand soldering much easier (although still many believe the opposite to be true) but now we are faced with BGA and other packaging forms which only have contacts on the bottom of the chip. | More and more semiconductors are produced in packages (the chip's case) which have become impossible to hand solder with a solder iron.

+ | 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/ | ||
