ESP32-S3-DevKitM-1-N8
by Espressif
The ESP32-S3-DevKitM-1 is an entry-level development board equipped with the ESP32-S3-MINI-1, a powerful, generic Wi-Fi + Bluetooth LE MCU module that features a rich set of peripherals, yet an optimized size. It’s an ideal choice for a wide variety of application scenarios related to the Internet of Things (IoT), such as embedded systems, smart homes, wearable electronics, etc. ESP32-S3-MINI-1 comes with a PCB antenna. This version is equipped with the ESP32-S3-MINI-1 with 8MB Flash.
Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitM-1 on a breadboard.
At the core of the module is an ESP32-S3FN8, an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. You can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds.
ESP32-S3FN8 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB Serial/Jtag, MCPWM, SDIO host, GDMA, TWAI® controller (compatible with ISO 11898-1, i.e. CAN Specification 2.0), ADC, touch sensor, temperature sensor, timers, and watchdogs, as well as up to 45 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB communication
There are three mutually exclusive ways to provide power to the board:
- USB-to-UART Port and ESP32-S3 USB Port (either one or both), default power supply (recommended)
- 5V and G (GND) pins
- 3v3 and G (GND) pins
Components:
- ESP32-S3-Mini-1: ESP32-S3-Mini-1 is a powerful, generic Wi-Fi + Bluetooth LE MCU module that has a rich set of peripherals. It provides acceleration for neural network computing and signal processing workloads. ESP32-S3-Mini-1 comes with a PCB antenna.
- 5V to 3.3V LDO: Power regulator that converts a 5V supply into a 3.3V output.
- Pin Headers: All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board for easy interfacing and programming. For details, please see Header Block.
- USB-to-UART Port: A Micro-USB port used for power supply to the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge.
- Native ESP32-S3 USB Port: ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. The interface is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB 1.1 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
- USB-to-UART Bridge: Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps.
- RGB LED: Addressable RGB LED, driven by GPIO48.
- 3.3V Power On LED: Turns on when the USB power is connected to the board.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
Install, Repair, or Update UF2 Bootloader
Latest version: 0.20.1
The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. If a UF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.)
It is not necessary to reinstall a UF2 bootloader you unless a BOOT drive is not visible when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader.
If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash .uf2 files onto the board. .bin files can be uploaded without a UF2 bootloader, using the ESP Web Flasher or esptool.py.
Note: update.uf2 files are not currently working on ESP32-S2 or ESP32-S3 boards.
Important: this will erase previously flashed firmware and sketches from the board, but needs to be perfomed only once.
The instructions here are general. We recommend you consult the manufacturer's board documentation for detailed instructions, which may be different.
- Unzip to find the file combined.bin.
- Place board in bootloader mode:
- Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
- Press and hold down the BOOT or 0 button.
- Press and release the RESET or RST button.
- Release the BOOT button.
- Upload combined.bin (Google Chrome 89 or newer):
- Open ESP Web Flasher in a new window/tab.
- Select 460800 Baud from the pull-down menu (top-right).
- Click Connect (top-right).
- Select the COM or Serial port from the pop-up window.
- After successful connection, click Erase.
- After successful erase, click any Choose a file..., then locate and select the combined.bin file unzipped earlier.
- After successfully choosing combined.bin, click Program.
- After the TinyUF2 firmware update is complete, press the RESET button on the board. A new drive BOOT should be visible in your file browser.
After installing the UF2 bootloader, enter the bootloader by double-clicking the reset button. On boards with an RGB status LED, tap reset once, wait for the LED to turn purple, and tap again before the purple goes away. On other boards, consult the board documentation.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to load or reload CircuitPython using the .uf2 file.
