Good noise suppression is essential. An additional capacitor can be added between the + and - of the supply. A 100 uF capacitor is more than sufficient. The ESP32 draws high peak currents (200 to 300 mA). The USB interface cannot supply this much current. This means you have to use an external power supply of sufficient size."<o:p></o:p></p><p class=MsoNormal>- sgh<br><br>On 01/28/2018 12:24 AM, Scott Hall wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>You're in luck!!
