I came across this cheap step-up regulator: CKCS BS01, sold anonymously as " Mini DC-DC Boost Step Up Converter" on some websites, smaller than MT3608.
It delivers 5/8/9/12 from input at least 2.5v lower.
In my case 3.7 lithium battery to 5V for my ESP32 cam
Does anybody have some experience with this regulator?
Thank you
@albertobangkok Do you have a picture of said converter? Or better, its datasheet in English? Generally, you would want to read the datasheet so you know what you are buying.
Also, a common practice in electronics is to have a battery that will supply HIGHER voltage than the logic voltage. An example of this is smartphones, which have 3.7v batteries and have 3.3v logic voltage. Your camera needs 5v, so you would want to have about 7v, which is then regulated down to 5v with an external regulator. You can then power your ESP32 module by connecting the 5v output to Vin, which will take care of the ESP and its camera.
Boost converters are very common. The one you mentioned would probably be fine.
