  • Convert a 5v PIR Motion Sensor to 3.3v for ESP8266

    Hello,I think you made a mistake : the voltage regulator on the board is a HT7133 so pin 2 is "power input". You have to solder your wire on pin 3, which is "power output". So why does your solution works ? It's because by injecting the 3.3V directly to the regulator you are bypassing the polarity protection diode and it's voltage drop.
