Getting Started

This section provides a brief introduction of ESP32-C6-DevKitC-1, instructions on how to do the initial hardware setup and how to flash firmware onto it.

Description of Components

ESPRESSIF-ESP32-C6-DevKitC-1-Development-Board-1

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

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.

Contents and Packaging

Retail orders

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: 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 ℑ
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 ESP32-C6-DevKitC-1 Schematic (PDF).

(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 chip power-up or system reset. For description and application of the strapping pins, please refer to ESP32-C6 Datasheet > Section Strapping Pins.
