ESP32-S3 N16R8 Devboard 16MB Flash and 8MB PSRAM

ESP32-S3 N16R8 Devboard with 16MB Flash and 8MB PSRAM

The ESP32-S3 N16R8 Devboard is a powerful full-size development board with 16MB external flash and 8MB PSRAM. The board features an Xtensa LX7 32-bit dual-core processor up to 240 MHz, 384 KB ROM, and 512 KB onboard SRAM. This makes it suitable for demanding Internet of Things (IoT) applications.

Key features

• WiFi 2.4 GHz (802.11 b/g/n) with 40 MHz bandwidth
• Bluetooth 5 Low Energy (BLE) and Bluetooth mesh support
• Two USB Type-C ports: CH343P serial interface and USB OTG
• Reset and boot buttons for easy operation
• Integrated RGB LED plus status LEDs for power (PWR), receive (RX), and transmit (TX)
• 44 programmable GPIO pins, with extensive peripherals such as SPI, I2S, I2C, PWM, ADC, UART, and SD/MMC host controller

Power options

The board can be powered in three ways:

• Via USB to UART port and/or ESP32-S3 USB port (recommended by default)
• Via 5V and GND pins
• Via 3.3V and GND pins

Performance and applications

The ESP32-S3 N16R8 DevKitC offers significantly better performance than traditional microcontrollers such as the STM32, thanks to the higher clock speed and larger flash memory. The combination of WiFi and Bluetooth makes the board ideal for IoT projects where wireless communication is essential.

The board supports multiple power-saving modes, including an ultra-low-power coprocessor (ULP), making it suitable for low-power applications.
