ESP32-C6 & ESP32-C6

[中文]

Note

  • The Strapping and USB pin definitions of ESP32-C6 and ESP32-C61 are exactly the same, and the hardware requirements for firmware burning are also exactly the same.

ESP32-C6 & ESP32-C61 support two firmware download methods: UART0 and USB.

Hardware Wiring

When using the UART0 pin to download the firmware, the following wiring conditions need to be met:

VDD     -> 3V3
GND     -> GND   (Common ground with the power supply board)
EN      -> Pull high   (Used for power-on startup, cannot be left floating)
GPIO8   -> Pull high   (Default is floating)
GPIO9   -> Pull low   (Default is ``high level``)
TXD0(GPIO16)    -> RX
RXD0(GPIO17)    -> TX

When using the USB pin to download the firmware, the following wiring conditions need to be met:

VDD     -> 3V3
GND     -> GND   (Common ground with the power supply board)
EN      -> Pull high   (Used for power-on startup, cannot be left floating)
GPIO8   -> Pull high   (Default is floating)
GPIO9   -> Pull low   (Default is ``high level``)
GPIO12  -> USB_D-
GPIO13  -> USB_D+

Note

  • After powering on the chip/module, you can check whether it has entered the Download Boot mode through the UART0 serial port.

  • When the chip is powered on, GPIO8 and GPIO9 cannot be low level at the same time.

Startup Conditions

  • The working voltage range of the ESP32-C6 & ESP32-C61 chip is 3.0 V ~ 3.6 V; when using a single power supply, it is recommended that the power supply voltage for the ESP32-C6 & ESP32-C61 series chips be 3.3 V, and the rated output current should be 500 mA or above.
