ESP32-S3 WiFi-Bluetooth Mini Development Board Arduino Projects

ESP32-S3 Mini Development Board w/ Wifi & Bluetooth

This ESP32-S3 development board is assembled with an original ESP32-S3-WROOM-1 module from Espressif, with 16MB Flash and 8MB PSRAM(ESP32-S3-WROOM-1-N16R8). It is a general-purpose Wi-Fi + Bluetooth® LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions. Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount the module on a breadboard.

The ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache. There is a RGB WS2812 LED that can be connected to IO48 (disconnected by default - see note below). It has a Red, Green and Blue LED that are individually addressable. There are plenty of examples on the internet showing how to drive a WS2812 LED. For example, Google "WS2812 Arduino" or "WS2812 c code".

Please Note: To connect the on board addressable LED to pin 48, close the solder-bridge marked ‘RGB’, next to the LED.
