Adafruit Metro ESP32-S2

What's Metro shaped and packed with innovation? Featuring an ESP32-S2 WiFi module, STEMMA QT connector for I2C devices, and a built-in Lipoly charger, the Adafruit Metro ESP32-S2 is the perfect match for your next IoT project. With native USB and substantial PSRAM, it's tailored for CircuitPython or Arduino, smoothly adding low-cost WiFi while ensuring shield-compatibility.

The ESP32-S2 is a 2.4 GHz Wi-Fi System-on-Chip (SoC) solution. While boasting native USB capabilities for advanced interfacing, it's also equipped for state-of-the-art power and RF performance, making it ideal for Internet of Things applications, wearable electronics, and smart homes. Its single-core 240 MHz chip might be slower than dual-core ESP32 counterparts, and doesn't support Bluetooth®.

The Metro's WROVER module includes 4 MB flash and 2 MB PSRAM, enabling vast data buffers. Power options abound: 6-12VDC barrel jack, USB type C, or Lipoly battery, with built-in charging through DC or USB. Additional features include MAX17048 precision battery monitoring, UNO-shape for easy shield connections, Reset and DFU buttons, optional serial debug pins, JTAG pads, and an On/Off switch. The STEMMA QT connector and integrated LEDs, alongside support for Arduino or CircuitPython, make it a versatile choice for developers.

Measuring 53.2mm x 72mm (2" x 2.8") and weighing 22.5g, this innovative board delivers powerful, compact solutions for varying application scenarios.
