[中文]
This user guide will help you get started with ESP32-C6-DevKitC-1 and will also provide
more in-depth informaon.
ESP32-C6-DevKitC-1 is an entry-level development board based on ESP32-C6-WROOM-1,
a general-purpose module with a 8 MB SPI flash. This board integrates complete Wi-Fi,
Bluetooth LE, Zigbee, and Thread funcons.
Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing.
Developers can either connect peripherals with jumper wires or mount ESP32-C6-DevKitC-1
on a breadboard.

Start Application Development
Before powering up your ESP32-C6-DevKitC-1, please make sure that it is in good condion
with no obvious signs of damage.
Required Hardware
ESP32-C6-DevKitC-1
USB-A to USB-C cable
Computer running Windows, Linux, or macOS
Note
Be sure to use a good quality USB cable. Some cables are for charging only and do not
provide the needed data lines nor work for programming the boards.
Software Setup
Please proceed to ESP-IDF Get Started, where Secon Installaon Step by Step will quickly
help you set up the development environment then flash an applicaon example onto your
board.
ESP-AT Support
The ESP32-C6-DevKitC-1 supports ESP-AT soware that provides a set of AT commands
with which you can quickly integrate wireless connecvity features into your product without
a need for embedded applicaon development of the module on this development board.
The soware is available as a pre-built binary that can be downloaded from ESP-AT
repository.
For more informaon about using ESP-AT, including informaon on how to customize pre-
built binaries, please refer to ESP-AT User Guide.

Power Supply Options
There are three mutually exclusive ways to provide power to the board:
USB Type-C to UART Port, default power supply
5V and GND pin headers

3V3 and GND pin headers
It is recommended to use the first opon: USB Type-C to UART Port.
Current Measurement
The J5 headers on ESP32-C6-DevKitC-1 (see J5 in Figure ESP32-C6-DevKitC-1 - front) can
be used for measuring the current drawn by the ESP32-C6-WROOM-1 module:
Remove the jumper: Power supply between the module and peripherals on the board is
cut off. To measure the module’s current, connect the board with an ammeter via J5
headers.
Apply the jumper (factory default): Restore the board’s normal funconality.
Note
When using 3V3 and GND pin headers to power the board, please remove the J5 jumper,
and connect an ammeter in series to the external circuit to measure the module’s current.
Header Block
The two tables below provide the Name and Funcon of the pin headers on both sides of the
board (J1 and J3). The pin header names are shown in Figure ESP32-C6-DevKitC-1 - front.
