WebSinking refers to grounding (sinking) an output pin connected to a load which is in turn connected to a higher voltage. The latter are mostly associated with open-drain outputs, which are either at ground (off) or high impedance (on). This allows them to ground a load that is connected to a voltage much higher than VCC. \$\endgroup\$ – http://www.mosaic-industries.com/embedded-systems/microcontroller-projects/raspberry-pi/gpio-pin-electrical-specifications WebLOW LEVEL range is -0.3V to 0.825V HIGH LEVEL range is 2.475V to 3.6V. But when I tested practically: LOW LEVEL range is 0V to 1.67V HIGH LEVEL range is 1.67V to 3.3V.
