Tell me please, if I connect to ESP32S3: 3 * OneWire sensors like DS18B20 + 3 * I2C sensors like SHT30 + 1 fast SPI sensor + 7" touch display with backlit + SD card + use it WiFi or Bluetooth a little = it will not overload ESP32S3 power supply?
After all this can ESP32S3 small board also power one more item which require: Voltage 12VDC, Current ~0.3A, Power 3.6W over voltage transformer as MT3608/MP1584EN/etc? Or this item can already overload ESP32S3 power supply thus it's better to power it externally?
At ESP32S3 datasheet part.4 Power there is too much info, not sure which tells about max power possibility for peripherals?
BTW which cheap&flat 5V->12V voltage transformer is better MT3608 or MP1584EN or another?
An ESP32S3 can provide zero power. Zero. It's just a chip. Something must supply power to it. Your question should be: can whatever power supply that is powering the ESP also power those other components? We can't answer that because we don't know what that power supply is.
I suggest you post links to the specs of the ESP board you plan to use and all of those sensors, so we can see exactly what models are involved and their capabilities and needs in terms of power.
And most importantly, tell us how you plan to actually power any of this?
You know it's normal practice when some info is absent to assume the most obvious option - board will be powered from classic USB 5V adapter which can handle up to 2A-3A. But I'm not sure that is save for ESP32 and other electronic on a such small board (and for analog data purity & stability) to pass such high power through such small boards?!
I have already named the names of most sensors. Screen maybe 4.3-5" IPS Capacitive touch.
So I'm asking what is the max A & W power throughput is SAVE for a such small ESP32 boards?!
nothing obvious there... if you had been on the forum long enough, you'd know.
that's not the issue.
The question is how your board will take the input current and route it to other components. Is there a regulator involved for example. which one is it, does it have limits... this varies rom board to board.
it could be 5V / 100A the board would still be fine and drawing just the current it needs. The question is wether the on board elements and tracks can withstand this current. You'll need to look at the datasheet or ask the vendor
