What's Metro-shaped and has an ESP32-S3 WiFi module? What has a STEMMA QT connector for I2C devices and a Lipoly charger circuit? What has your favorite Espressif WiFi microcontroller and lots of memory for your next IoT project?

That's right - it's the new **Adafruit Metro ESP32-\*S3\***! With native USB and a load of PSRAM, this board is perfect for use with CircuitPython or Arduino to add low-cost WiFi while retaining shield compatibility.

The ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the [Internet of Things (IoT)](https://www.adafruit.com/category/342), [wearable electronics](https://www.adafruit.com/category/65), and smart homes.

The Metro ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32's dual-core. However, there is no Bluetooth **Classic** support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module we are using on the Metro comes with massive 16 MB flash and 8 MB PSRAM, as well as lots of 512KB of SRAM so it's perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It's also great for use in ESP-IDF or with Arduino support.

**Features:**
|
|
|
|
- **ESP32-S3 Dual Core 240MHz Tensilica processor** - the next generation of ESP32-Sx, with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!
|
|
- **Mini module** has FCC/CE certification and comes with 16 MByte of Flash, 8 MByte PSRAM
|
|
- **Power options** - USB type C **or** Lipoly battery
|
|
- **Built-in battery charging** when powered over USB-C
|
|
- **LiPoly battery monitor** - MAX17048 chip actively monitors your battery for voltage and state of charge / percentage reporting over I2C
|
|
- **Reset and DFU** (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don't need a separate cable!)
|
|
- **JTAG 2x5 Header** for more intense debugging
|
|
- **Serial debug output pins** (optional, for checking the hardware serial debug console)
|
|
- **STEMMA QT** connector for I2C devices, with switchable power, so you can go into low power mode.
|
|
- **On/Charge/User** LEDs + status **NeoPixel** with pin-controlled power for low power usage
|
|
- **Low Power friendly**! In deep sleep mode we can get down to ~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S3 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C power for the lowest quiescent current draw.
|
|
- **Works with ESP-IDF, Arduino** **or CircuitPython**
