00 — Overview

What the ESP32-S3-WROOM-1 family does

The ESP32-S3-WROOM-1x family are Wi-Fi and Bluetooth 5 MCU modules featuring a dual-core 32-bit LX7 processor running up to 240 MHz. These devices integrate 384 KB ROM, 512 KB SRAM, and up to 16 MB of PSRAM or QuadSPI flash. Operating on a 3.0 to 3.6 V supply, they support 802.11 b/g/n with speeds up to 150 Mbps and Bluetooth LE at 2 Mbps. The modules include extensive peripherals like GPIO, SPI, I2C, and USB 2.0 OTG. They are designed for AIoT applications such as wake-word detection, voice command recognition, face detection, smart home control, and smart appliances. Variants span commercial, industrial, and military temperature grades from –40°C to 105°C.
