ESP32-S3 DevKitC-1 N8R2 – Dual USB-C Wi-Fi + BLE Development Board

 Introduction

The ESP32-S3 DevKitC-1 N8R2 pairs the ESP32-S3 dual-core LX7 MCU with 8 MB QSPI Flash + 2 MB QSPI PSRAM, giving you enough headroom for advanced Wi-Fi/BLE projects, UI work, and ML/DSP sketches. The board exposes two independent USB functions—a classic USB-to-UART bridge and the SoC’s native USB 2.0 FS (USB-Serial-JTAG/OTG)—so you can power, flash, debug, and even make USB devices with a single cable. Most GPIOs are broken out on breadboard-friendly headers, with Boot/Reset buttons and a built-in RGB LED (GPIO48) for status.

 What’s Included

  • ESP32-S3-DevKitC-1 board populated with ESP32-S3-WROOM-1-N8R2 module × 1 (8 MB Flash + 2 MB PSRAM)

 Key Features

  • Dual-core LX7 up to 240 MHz: optimized for DSP/AI kernels with vector instructions.

  • Wireless combo: Wi-Fi 2.4 GHz (802.11 b/g/n) + Bluetooth 5 LE.

  • Two USB paths on board: USB-to-UART for serial/flashing and native USB 2.0 FS / USB-Serial-JTAG for flashing, debug, and USB device/host projects.

  • Memory for real apps: 8 MB Flash + 2 MB PSRAM (N8R2 variant).

  • Breadboard-friendly headers: most module GPIOs are broken out for quick prototyping.

  • On-board conveniences: Boot + Reset buttons, RGB LED on GPIO48, 5 V→3.3 V LDO regulator.

 Specifications

Parameter Value / Notes
MCU / Module ESP32-S3-WROOM-1-N8R2 (dual-core LX7 up to 240 MHz)
Wireless 2.4 GHz Wi-Fi (b/g/n), Bluetooth 5 LE
Memory 8 MB QSPI Flash + 2 MB QSPI PSRAM (module)
USB USB-to-UART + native USB 2.0 FS / USB-Serial-JTAG (OTG) on board
I/O Up to 36 GPIOs on the module; most available on headers +1
Indicators/Controls RGB LED (GPIO48), Boot, Reset
Power Via either USB port, 5 V pin, or 3V3 pin (exclusive)

 Compatibility & Tips

  • Two ways to flash: use the UART port (legacy method) or the native USB-Serial-JTAG port for faster, driver-light flashing and JTAG debug.

  • If you use native USB in your firmware, you can enumerate as CDC, HID, MSC, etc. (USB 2.0 FS).

  • Some SPI-flash/PSRAM pins are internally used by the module—plan your GPIO map accordingly.

 Use Cases

  • Wi-Fi + BLE gateways, HID gadgets over native USB, display/audio nodes, sensor hubs, TinyML/DSP demos, and beginner-friendly coursework labs.

 Safety & Handling

  • Power from one source at a time (USB or 5 V pin or 3V3 pin). Avoid back-powering.

  • Observe ESD care; do not exceed absolute maximum ratings on GPIOs.

 FAQ

Q1: What exactly does N8R2 mean?
A: N8 = 8 MB QSPI Flash; R2 = 2 MB QSPI PSRAM in the module variant.

Q2: Can I power and program from either USB port?
A: Yes. Both ports can power the board; use UART for classic flashing or native USB-Serial-JTAG for flashing/debug and USB device features.

Q3: Does the board break out most GPIOs?
A: Yes—most module pins are on headers; SPI flash/PSRAM pins remain dedicated.
