ESPRESSIF ESP32-C6-DevKitC-1 v1.2 Development Board
The older version: ESP32-C6-DevKitC-1 v1.1 This user guide will help you get started with ESP32-C6-DevKitC-1 and will also provide more in-depth information. ESP32-C6-DevKitC-1 is an entry-level development board based on ESP32-C6- WROOM-1(U), a general-purpose module with an 8 MB SPI flash. This board integrates complete Wi-Fi, Bluetooth LE, Zigbee, and Thread functions. 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.
The document consists of the following major sections

Getting Started
This section provides a brief introduction to ESP32-C6-DevKitC-1, instructions on how to do the initial hardware setup, and how to flash firmware onto it.
Description of Components
The key components of the board are described in a clockwise direction
| Key Component | Description |
|---|
ESP32-C6-WROOM- 1 or ESP32-C6- WROOM-1U
| ESP32-C6-WROOM-1 and ESP32-C6-WROOM-1U are general-
purpose modules supporting Wi-Fi 6 in 2.4 GHz band, Bluetooth 5, and IEEE 802.15.4 (Zigbee 3.0 and Thread 1.3). They are built around the ESP32-C6 chip, and comes with a 8 MB SPI flash. ESP32-C6- WROOM-1 uses on-board PCB antenna, whereas ESP32-C6-WROOM- 1U uses external antenna connector. For more information, see ESP32- C6-WROOM-1 Datasheet.
Pin Header
| All available GPIO pins (except for the SPI bus for flash) are broken out to
the pin headers on the board.
5 V to 3.3 V LDO| Power regulator that converts a 5 V supply into a 3.3 V
output.
3.3 V Power On LED| Turns on when the USB power is connected to the board.
USB-to-UART
Bridge
|
Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps.
ESP32-C6 USB
Type-C Port
| The USB Type-C port on the ESP32-C6 chip compliant with USB 2.0 full speed. It is capable of up to 12 Mbps transfer speed (Note that this port does not support the faster 480 Mbps high-speed transfer mode). This port is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB protocols, as well as for JTAG debugging.
Boot Button
| Download button. Holding down Boot and then pressing Reset initiates
Firmware Download mode for downloading firmware through the serial port.
Reset Button| Press this button to restart the system.
USB Type-C to UART Port
| Used for power supply to the board, for flashing applications to the chip,
as well as the communication with the ESP32-C6 chip via the on- board USB-to-
UART bridge.
RGB LED| Addressable RGB LED, driven by GPIO8.
J5
| Used for current measurement. See details in Section Current Measurement.
Start Application Development
Before powering up your ESP32-C6-DevKitC-1, please make sure that it is in
good condition 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, which will quickly help you set up the
development environment then flash an application example onto your board.
Hardware Reference
Block Diagram
The block diagram below shows the components of ESP32-C6-DevKitC-1 and their
interconnections.
Power Supply Options
There are three mutually exclusive ways to provide power to the board:
- USB Type-C to UART Port and ESP32-C6 USB Type-C Port (either one or both), default power supply (recommended)
- 5V and GND pin headers
- 3V3 and GND pin headers
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(U)
module:
- Remove the jumper: The 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 functionality.
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 Function 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. The numbering is the same as in the

- (1,2,3,4,5) MTMS, MTDI, GPIO8, GPIO9, and GPIO15 are strapping pins of the ESP32-C6 chip. These pins are used to control several chip functions depending on binary voltage values applied to the pins during the chip power-up or system reset. For a description and application of the strapping pins, please refer to ES P32-C6 Datasheet > Section Strapping Pins.
