NEW GUIDE: Adafruit Metro ESP32-S3 #Metro #ESP32 #AdafruitLearningSystem @Adafruit
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 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 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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
