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.
