What has your favorite Espressif WiFi microcontroller and lots of memory for your next IoT project?\u003c\/p\u003e\n\u003cp\u003eThat's right - it's the new Adafruit Metro ESP32-S3! With native USB and a load of octal PSRAM, this board is perfect for use with CircuitPython or Arduino to add low-cost WiFi while retaining shield compatibility.\u003c\/p\u003e\n\u003cp\u003eThe 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), wearable electronics, and smart homes.\u003c\/p\u003e\n\u003cp\u003eThe 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 WROOM 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.\u003c\/p\u003e\n\u003ch3\u003eRevision History\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of 7th March 2024\u003c\/strong\u003e - We've fixed this hardware to be revision B which has changed the NeoPixel pin and the SPI\/SD card pins to no longer use the same pins as the octal PSRAM.
