ESP32-S3 N16R8 Core Development Board with CH340K Type-C USB – 16MB Flash, 8MB PSRAM, WiFi & Bluetooth 5 LE

The ESP32-S3 N16R8 Core Development Board with CH340K Type-C USB is designed for wireless embedded development, IoT systems, automation, robotics, smart devices, and general ESP32-S3 prototyping.

The ESP32-S3 platform provides a dual-core 32-bit Xtensa LX7 processor operating at up to 240MHz, along with 512KB internal SRAM, 384KB ROM, and 16KB RTC SRAM. It also provides integrated 2.4GHz WiFi and Bluetooth 5 LE connectivity.

The N16R8 configuration is particularly useful when additional external memory is required. Espressif specifies 16MB Flash and 8MB Octal-SPI PSRAM for the ESP32-S3-WROOM-1-N16R8 module configuration.

How to Use

1. Install Arduino IDE, ESP-IDF, or MicroPython according to your development requirements.
2. Install the appropriate CH340 USB driver if your computer does not automatically recognize the USB interface.
3. Connect the board to a computer using a suitable USB Type-C data cable.
4. Select the appropriate ESP32-S3 board configuration in your development environment.
5. Upload your firmware and use the serial monitor for debugging.
6. Connect sensors, displays, modules, or other peripherals through the available GPIO, I2C, SPI, UART and other interfaces.
7. Configure WiFi or Bluetooth functionality according to your application.

Important Notes

• The N16R8 designation means 16MB Flash + 8MB PSRAM; Espressif documents this configuration for the ESP32-S3-WROOM-1 family.
• The ESP32-S3 module itself operates from a low-voltage supply; do not apply 5V directly to 3.3V GPIO pins.
• 5V via USB Type-C refers to the development board's USB power input, not the native ESP32-S3 I/O voltage.
• A USB data cable is required for programming; charge-only cables will not work for data transfer.
• CH340K drivers may be required depending on the operating system.
• Actual GPIO availability and pin assignments depend on the specific development-board design.
• Avoid applying excessive voltage to GPIO pins.
• Motors, relays, solenoids and other high-current loads should be controlled through suitable driver circuits rather than directly from GPIO.
• Board dimensions are approximate and may vary slightly between manufacturing batches.
• Product images are for illustration; the actual PCB layout, component markings, and connector placement may vary.
