What you will get: 2 X ESP32-S3-DevKitC-1-N8R8 Development Board. 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. ESP32-S3 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO host, GDMA, TWAI controller (compatible with ISO 11898-1), 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. At the core of the modules is an ESP32-S3 series of SoC, 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. 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-DevKitC-1 on a breadboard. There's a debug UART/USB port and a separate native USB port, so you can upload/debug/USB all at once. Note: The S3 is similar to the ESP32-S2, But adds a dual-core and Blue-tooth LE (not classic!) However, there is minimal support for this dev board. For example, as of the time of this writing, there is NO Arduino or Circuit-Python support, ESP IDF ONLY! Please purchase if you're doing development with the S3. The ESP32-S3-DevKitC-1 is an entry-level development board equipped with ESP32-S3-WROOM-1, a general-purpose Wi-Fi + Blue-tooth LE MCU module that integrates complete Wi-Fi and Blue-tooth LE functions. This version is equipped with the ESP32-S3-WROOM-1 with 8MB Flash and 8 MB PSRAM.
