SeeedXIAO ESP32-S3
Overview
The 113991114 is a Seeed Studio XIAO ESP32-S3 development board featuring a dual-core Xtensa LX7 processor running at up to 240MHz. This compact module integrates 2.4GHz Wi-Fi and Bluetooth 5.0 (BLE) connectivity with a U.FL antenna connector for extended range. Despite its small 21mm x 17.5mm footprint, it includes 8MB of PSRAM, 8MB of flash memory, and an integrated battery charging circuit.
Why Choose This Part
The board offers a high memory-to-size ratio with 8MB of both Flash and RAM in a thumb-sized package. It simplifies power management with a built-in battery charging chip and supports flexible wireless configurations via the included U.FL antenna.
Applications
Key Specifications
Getting Started
Engineers can program the board using the Arduino IDE with the ESP32 board manager or the official ESP-IDF toolchain. The hardware is breadboard-compatible with 11 GPIOs and features a USB Type-C interface for power and programming. For battery-powered operation, connect a 3.7V lithium polymer battery to the dedicated solder pads on the underside.
Also Consider
Arduino
- Uses the same ESP32-S3 SoC but in the classic Nano form factor for compatibility with Nano-sized shields and the Arduino ecosystem.
Espressif Systems
- The official Espressif evaluation board providing access to more GPIO pins and integrated USB-to-UART bridges.
