## Description

The ESP-WROOM-32 is Espressif's powerful Wi-Fi, Bluetooth Classic, and BLE module built around the ESP32 dual-core processor. It's a versatile platform for IoT applications ranging from low-power sensor networks to demanding tasks like voice encoding, music streaming, and MP3 decoding. This is the bare module with 1.27 mm pitch castellated pads — designed for soldering onto a custom PCB with supporting circuitry. Certified for FCC, CE, IC, MIC (Telec), KCC, and NCC. Warning: This is the raw module only — not a development board. You will need to design or use a carrier board with power regulation, USB interface, and boot/reset circuitry. If you want a ready-to-use board, look for an ESP32 development board instead. Key Features Dual-Core Xtensa LX6 – Two 32-bit processors for parallel processing Wi-Fi 802.11 b/g/n – Up to 150 Mbps, Station/SoftAP/P2P modes Bluetooth v4.2 – Both Classic BR/EDR and BLE Rich Peripheral Set – UART, SPI, SDIO, I2C, I2S, PWM, ADC, DAC, touch sensor, Hall sensor, and more Security – WPA/WPA2/WPA2-Enterprise, AES/RSA/ECC/SHA encryption Network Protocols – IPv4, IPv6, SSL, TCP/UDP/HTTP/FTP/MQTT Specifications Processor: Dual Xtensa 32-bit LX6 ROM: 448 KB (boot and core functions) SRAM: 520 KB on-chip + 8 KB RTC SLOW + 8 KB RTC FAST eFuse: 1 Kbit (256-bit MAC) Wi-Fi: 802.11 b/g/n/d/e/i/k/r (up to 150 Mbps) Bluetooth: v4.2 BR/EDR + BLE Operating Voltage: 2.2–3.6 V Typical Current: 80 mA Operating Temperature: −40 °C to +85 °C Dimensions: 18 × 25.5 × 2.8 mm Pin Pitch: 1.27 mm PCB Thickness: 0.8 ± 0.1 mm Interfaces SD card, UART, SPI, SDIO, I2C LED PWM, Motor PWM, I2S, IR GPIO, Capacitive Touch Sensor ADC, DAC, Hall Sensor, Temperature Sensor Package Contents 1× ESP-WROOM-32 Module Resources Datasheet (PDF)
