## Description

The Adafruit Metro ESP32-S3 brings the powerful dual-core ESP32-S3 to the familiar Metro/UNO shield-compatible form factor. With 16 MB flash, 8 MB PSRAM, and 512 KB SRAM, this board has the memory to handle demanding CircuitPython, Arduino, or ESP-IDF projects with WiFi and Bluetooth LE connectivity. Native USB support means the Metro ESP32-S3 can act as a keyboard, mouse, MIDI device, or disk drive. A built-in LiPo battery charger and MAX17048 fuel gauge provide complete battery management with voltage and state-of-charge monitoring, while deep sleep mode draws as little as ~100 µA for battery-powered deployments. Key Features ESP32-S3 Dual-Core 240 MHz Processor – With native USB and AI acceleration support 16 MB Flash + 8 MB PSRAM + 512 KB SRAM – Massive memory for large buffers and complex applications WiFi + Bluetooth LE – 2.4 GHz 802.11 b/g/n and BLE connectivity Native USB – Acts as keyboard, mouse, MIDI device, or disk drive Metro/UNO Shield Compatible – Standard form factor for plug-in shields USB-C + LiPo Battery Power – Dual power options with built-in battery charging MAX17048 Battery Monitor – Active voltage and charge percentage tracking over I2C Ultra-Low Power Sleep – ~100 µA deep sleep current from LiPo connection STEMMA QT / Qwiic Port – Switchable-power I2C connector for low-power modes Status LEDs + NeoPixel – On, Charge, and User LEDs with pin-controlled NeoPixel power Reset & DFU Buttons – Quick access to ROM bootloader via USB serial JTAG 2×5 Header – For advanced debugging FCC/CE Certified Module – Ready for product development Ideal For WiFi and BLE IoT projects with shield compatibility Battery-powered portable wireless devices CircuitPython, Arduino, or ESP-IDF development USB HID projects (keyboard, mouse, MIDI) AI and machine learning edge applications Package Contents 1× Adafruit Metro ESP32-S3 (with headers) Tip: For lowest power consumption in sleep mode, turn off the NeoPixel and external I2C power via the switchable STEMMA QT connector.
