This user guide will help you get started with ESP32-DevKitM-1 and will also provide more in-depth information.
|
|
|
|
ESP32-DevKitM-1 is an ESP32-MINI-1(1U)-based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Users can either connect peripherals with jumper wires or mount ESP32-DevKitM-1 on a breadboard.

Start Application Development
|
|
----------------------------------
|
|
|
|
Before powering up your ESP32-DevKitM-1, please make sure that it is in good condition with no obvious signs of damage.
|
|
|
|
|
|
Required Hardware
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- ESP32-DevKitM-1
|
|
- USB 2.0 cable (Standard-A to Micro-B)
|
|
- Computer running Windows, Linux, or macOS
|
|
|
|
|
|
Software Setup
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Please proceed to :doc:`../../get-started/index`, where Section :ref:`get-started-step-by-step` will quickly help you set up the development environment and then flash an application example onto your ESP32-DevKitM-1.
|
|
|
|
.. attention::

Power Source Select
|
|
----------------------
|
|
|
|
There are three mutually exclusive ways to provide power to the board:
|
|
|
|
* Micro USB port, default power supply
|
|
* 5V and GND header pins
|
|
* 3V3 and GND header pins
|
|
|
|
.. warning::
|
|
|
|
- The power supply must be provided using **one and only one of the options above**, otherwise the board and/or the power supply source can be damaged.
|
|
- Power supply by micro USB port is recommended.
|
|
|
|
|
