Moduł ESP32 S3 Płytka DevKit WiFi BLE 5.0 IoT 2x USB-C 16MB Flash 8MB PSRAM

ESP32-S3-N16R8 development module compatible with Arduino IDE

Advanced development module equipped with the modern ESP32-S3 microcontroller. The board is a highly capable foundation for artificial intelligence systems, automation, and the Internet of Things (IoT). The device integrates wireless Wi-Fi connectivity and the Bluetooth Low Energy BLE 5.0 standard.

Thanks to large 16MB Flash memory and 8MB PSRAM operating in Octal SPI mode, the module handles extensive databases and algorithms without difficulty. Two independent USB-C ports provide direct UART serial communication and native USB-OTG interface support, which significantly simplifies software development and testing.

Key technical features

• Dual-core architecture: High-performance 32-bit Xtensa LX7 processor running at 240MHz.
• Expanded memory: The N16R8 version offers 16MB Flash memory and 8MB fast OPI PSRAM operational memory.
• Dual USB-C interface: Enables simultaneous board power supply and easy debugging with a computer.
• Built-in indication: Integrated addressable WS2812B RGB LED connected to the I/O line.
• Physical control buttons: The board features BOOT and RESET buttons that make it easy to enter programming mode.

Benefits

• High computational performance ideal for applications requiring real-time processing of large amounts of data.
• Wide communication capabilities thanks to built-in Wi-Fi and Bluetooth 5.0 network modules.
• Sufficient memory for complex program code, extensive libraries, and large operational buffers.
• Convenient connection and power supply using the common, modern USB-C connector standard.
• Full compatibility with many popular development environments designed for ESP32 and Arduino.

Example applications

• Creating advanced network nodes and smart gateways in home automation systems.
• Building Edge AI devices that run image or speech recognition algorithms locally at the network edge.

User tips

Communication with a computer and firmware upload require a USB-C cable that supports full data transfer. The included pin headers (goldpin) must be soldered by the user to the appropriate solder pads on the PCB.

Connecting the module to fast mains chargers with Power Delivery or Quick Charge may result in higher voltage being applied and permanent damage to the chip - always use standard 5V power supplies.

If you have problems uploading firmware, you can safely force the module into bootloader mode by holding the BOOT button and then briefly pressing the RESET button.
