網頁2024年11月13日 · If other chips require 5V signals from EP32, use a level shifter. ESP only outputs 3.3 V max. on an output pin. Some 5V chips may work with that (most will have a high level input voltage of less than 3V), but you should consult the data sheets to be sure. Note: a level shifter is a 74HCT14 with two gates in tandem. 網頁2024年4月12日 · Traditional step-down switching regulators can have difficulty running from the 3.3V supply, because affordable power MOSFETs generally require 5V gate drive to work efficiently. Two attractive solutions to generating 2.5V or less from a 3.3V supply are possible using the LTC1649 and the LTC1430A .
