quisqueya/ESP8266-GPIO-Extender-Plus
Expands the NodeMCU module GPIO to 48 pins (16 digital outputs, 16 digital inputs, and 16 analog inputs) using two CD4099B latch 8-bit chips to provide 16 digital output pins and two CD74HC4067 multiplexer/de-multiplexer to provide 16 digital inputs and 16 analog inputs . These output pins have persistant states, meaning that they keep the state that you assign them independent of each other. A CD74HC4067 multiplexer/de-multiplexer breakout module is used to provide 8 digital inputs and 8 analog inputs. The two CD4099B and the CD74HC4067 chips share three of the NodeMCU GPIO (D1, D2, and D3) like kind of a common bus.
