ESP32-S3 Board, 8MB Flash, 2MB RAM, USB Type-C, PCB Antenna

The ESP32-S3 development board is assembled with an original ESP32-S3-WROOM-1 module from Espressif, with 8MB Flash and 2MB PSRAM(ESP32-S3-WROOM-1-N8R2). It is a general-purpose Wi-Fi Bluetooth® LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions. PLEASE NOTE: The pin headers are yellow(as shown in photos) or red. 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 the module on a breadboard. The ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache. There is a RGB WS2812 LED connected to IO38. It has a Red, Green and Blue LED that are individually addressable. There are plenty of examples on the internet showing how to drive a WS2812 LED. For example, Google "WS2812 Arduino" or "WS2812 c code". This module has 2 USB Type C connectors. The one is used to power the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge. It is connected to a UART of the ESP32 chip via a CH340 chip. The second USB connector is connected to the ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. It can also be used to power 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. Key Component Description ESP32-S3-WROOM-1-N8R2 The ESP32-S3-WROOM-1 is a powerful, generic Wi-Fi Bluetooth LE MCU modules that have a rich set of peripherals. It provide acceleration for neural network computing and signal processing workloads. It comes with a PCB antenna. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V 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 USB Type-C 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. 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. 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. USB-to-UART Bridge Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps. RGB LED Addressable RGB LED, driven by GPIO38. 3.3 V Power On LED Turns on when the USB power is connected to the board.
