ESP32-S3 DevKitC-1 N16R8

Overview

A DevKitC-1-style development board built on the ESP32-S3-WROOM-1-N16R8 module. The 16 MB flash and 8 MB PSRAM leave room for large firmware, web interfaces, camera and display frame buffers, audio processing and machine-learning experiments.

The dual-core Xtensa LX7 processor runs at up to 240 MHz, with 2.4 GHz Wi-Fi and Bluetooth 5 (LE) built in. One USB-C port connects through a USB-to-UART bridge for programming and serial monitoring; the other connects to the ESP32-S3's native USB for USB device and OTG use.

Key Features

• ESP32-S3-WROOM-1-N16R8 module: 16 MB flash, 8 MB octal PSRAM
• Dual-core Xtensa LX7 up to 240 MHz, 512 KB SRAM
• 2.4 GHz Wi-Fi and Bluetooth 5 (LE)
• Two USB-C ports: USB-to-UART and native USB/OTG
• BOOT and RESET buttons, onboard RGB LED
• Pre-soldered 2.54 mm headers for breadboard use

Typical Applications

• IoT devices and Wi-Fi dashboards
• Camera, display and touchscreen projects
• USB HID devices such as custom keyboards and controllers
• Audio and voice projects
• Machine-learning and sensor-fusion experiments

Compatibility

Programmable with ESP-IDF, the Arduino IDE (ESP32 board package), PlatformIO and MicroPython. Select a board profile with 16 MB flash and octal (OPI) PSRAM to use the full memory.

Important Notes / Safety

• The GPIO pins are 3.3 V logic and are not 5 V tolerant. Use level shifting for 5 V modules.
• Some GPIOs are used by the flash and PSRAM and are not free for general use; check a pinout before wiring.
