SAFE LISTING TITLE

3-10PCS ESP32-S3 Development Board 44Pin Type-C WiFi BLE N16R8 16MB Flash 8MB PSRAM N8R2 8MB Flash 2MB PSRAM


PRODUCT OVERVIEW

Compact 44-pin development board built around an ESP32-S3 series controller. It combines a dual-core processor, 2.4 GHz wireless networking, BLE connectivity, external memory options and Type-C connectivity for embedded development, automation, sensor, display and IoT projects.


AVAILABLE MEMORY OPTIONS

- N8R2: 8 MB Flash + 2 MB PSRAM
- N16R8: 16 MB Flash + 8 MB PSRAM

Please select the required memory version before ordering. The supplied version is determined by the selected product option.


KEY FEATURES

- Dual-core 32-bit controller with a clock speed of up to 240 MHz
- 2.4 GHz 802.11 b/g/n wireless networking
- BLE 5 low-energy wireless connectivity
- 44-pin development board layout
- Two Type-C connectors for power, data and flashing workflows, subject to the selected connection mode
- Support for common interfaces such as GPIO, ADC, PWM, UART, I2C, I2S and SPI
- Suitable for embedded control, sensor nodes, smart-device prototypes, display projects and DIY electronics


MEMORY COMPATIBILITY

Larger-memory versions may run projects originally configured for smaller-memory versions when the board profile, partition layout, pin mapping and firmware settings are compatible. Reconfiguration or recompilation may still be required. Always select the correct Flash and PSRAM settings before uploading firmware.


PROGRAMMING GUIDE

1. Install a development environment and board-support package compatible with the ESP32-S3 series.
2. Connect the board with a data-capable Type-C cable.
3. Select the appropriate S3 board profile, USB or UART mode, serial port and memory configuration.
4. Compile and upload the program.
5. If uploading fails, check the selected port, cable, driver, boot mode and Flash/PSRAM settings.


TECHNICAL NOTES

- The controller supports multiple digital and analog peripherals; the interfaces available to the user depend on the actual board routing and selected firmware configuration.
- Flash and PSRAM capacity varies by model.
- Use the board markings and supplied wiring information when connecting power or external devices.
- A data-capable USB cable is required for programming; a charge-only cable cannot transfer firmware.
- Product appearance and component layout may vary slightly between production batches without affecting the selected model specifications.


PACKAGE CONTENTS

- Development board quantity: according to the selected 3-10PCS option
- Cables, headers and other accessories are not included unless shown in the selected package option.
