I would just like to ask if this microcontroller can power or can manage 2 servos, 2 motors, and 2 hc-sr04 ultrasonic distance sensor combined? Also, does this board come with a bluetooth module?

  • Thanks for the answer @StarCat but how would I do the "logic level translation"? Jul 29, 2021 at 7:08
  • Easiest would be to use the little 4-channel bidirectional level converters. Sometimes a simple voltage divider made out of two resistors would be enough (5V output to 3.3V input) and some 5V peripherals are 3.3V tolerant.

The ESP32 has more than enough free GPIOs to manage those peripherals. Also, the ESP32 does indeed come with a bluetooth module.

Your question about powering these peripherals very much depends on their power requirements. I would not count on being able to run motors or servos from the internal power supply of a NodeMCU board, so you would need an external supply.

Also, note that the ESP32 is a 3.3V device and might require logic level translation if you’re using 5V peripherals.
