I am trying to use the #2808 Mini Pushbutton Power Switch to switch power to a Nodemcu dev board. I am using a 2XAA battery pack at around ~3V attached to the Vin of the power switch, and the Vout of the switch attached to the 3.3V pin of the NodeMCU. The Nodemcu has a basic program which boots up, connects to wifi, and sends a message via MQTT.
I notice that when the NodeMCU boots (when I press the power switch button), the voltage that it is getting from the switch drops to around 2V and it does not function. If I connect the batteries directly to the NodeMCU, it works fine, with the voltage around 3V. Does the #2808 really cause this much voltage drop? The NodeMCU typically uses about 80mA.
