ESP32-C6-DevKitM-1 is an entry-level development board based on ESP32-C6-MINI-1(U), a general-purpose module with a 4 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, so developers can either connect peripherals with jumper wires or mount ESP32-C6-DevKitC-1 on a breadboard as per their needs. The board can be used in applications such as general-purpose low-energy IoT sensor hubs, general-purpose low-energy IoT data loggers, industrial automation, health care, consumer electronics, and smart agriculture.

ESP32-C6-DevKitM-1 is built around ESP32-C6, a RISC-V 32-bit single-core CPU that operates at up to 160 MHz, and integrates a rich set of peripherals. Users can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes.

Key Component Description
ESP32-C6-MINI-1 or ESP32-C6-MINI-1U ESP32-C6-MINI-1 and ESP32-C6-MINI-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). ESP32-C6-MINI-1 comes with an on-board PCB antenna, whereas ESP32-C6-MINI-1U comes with an external antenna connector. The module is built around the ESP32-C6FH4 chip, which has a 4 MB flash in the chip's package. For more information, see ESP32-C6-MINI-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 5V supply into a 3.3V output.
3.3 V Power on LED Turns on when the USB power is connected to the board.
USB-to-UART Bridge Single-chip USB-to-UART bridge provides transfer rates up to 3 Mbps.
ESP32-C6 USB Type-C Port The USB Type-C port on the ESP32-C6 chip is 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 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 reset 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.

The differences between ESP32-C6-DevKitM-1 and ESP32-C6-DevKitC-1-N8

The ESP32-C6-DevKitM-1 is based on the ESP32-C6-MINI-1 (U) module, which has a 4 MB SPI flash, while the ESP32-C6-DevKitC-1-N8 is equipped with the ESP32-C6-WROOM-1 module, which has an 8 MB flash.

The amount of flash memory can affect the amount of data that can be stored on the board and the complexity of the programs that can be run on it.
