At its core is the ESP32-D0WDQ6 chip featuring a dual-core Xtensa LX6 processor adjustable from 80MHz to 240MHz with 448KB ROM and 520KB SRAM. The module integrates 4MB SPI flash and a 40MHz crystal oscillator. Wi-Fi supports 802.11 b\/g\/n up to 150Mbps with 20.5dBm output power, while Bluetooth 4.2 supports BR\/EDR and BLE with Class-1\/2\/3 transmitters. The rich peripheral set includes capacitive touch sensors, SD card host, Ethernet MAC, high-speed SPI, UART, I2S, I2C, and motor control PWM.","working_principle":"The ESP32-WROOM-32 integrates a dual-core Xtensa LX6 processor where each core can be independently controlled and clocked. The Wi-Fi subsystem handles 802.11 b\/g\/n MAC and baseband processing with a dedicated RF chain operating in the 2.4GHz band. The Bluetooth subsystem supports both classic BR\/EDR and BLE with hardware link layer controllers. The GPIO matrix allows flexible peripheral-to-pin mapping. Power management includes multiple sleep modes: active, light sleep, and deep sleep (less than 5uA). The RTC subsystem can operate during deep sleep, enabling wake-up from GPIO, timer, or touch events. Hardware cryptographic accelerators support AES, RSA, ECC, and SHA for secure communication.","pin_description":"
