## Description

The ESP-WROOM-32 is Espressif's flagship WiFi + Bluetooth Classic + BLE module, built around the dual-core Tensilica LX6 microprocessor. It targets a wide variety of applications from low-power sensor networks to demanding tasks such as voice encoding, music streaming, and MP3 decoding — all in a compact, shielded package. This is the bare module only, intended for integration into custom PCB designs. You'll need to solder it onto a carrier board with supporting circuitry (voltage regulation, boot/reset buttons, USB-serial interface). The module is FCC, CE, IC, MIC (Telec), KCC, and NCC certified. Key Features Dual-Core Processor – Tensilica LX6 running at up to 240 MHz WiFi – 802.11 b/g/n, 2.4 GHz Bluetooth – Classic and BLE 4.2 dual-mode Memory – 520 KB SRAM, 4 MB flash Rich Peripherals – GPIO, ADC, DAC, SPI, I2C, I2S, UART, PWM, and more Certified – FCC, CE, IC, MIC (Telec), KCC, NCC Warning: This is the bare module only — not a development board. It requires soldering onto a custom PCB with supporting circuitry. Recommended for experienced users comfortable with PCB design and the ESP-IDF or Arduino toolchain. Ideal For Custom PCB designs requiring WiFi and Bluetooth IoT sensor networks and connected devices Audio streaming and voice processing projects Production-ready embedded wireless applications Package Contents 1× ESP-WROOM-32 Module Resources Arduino-ESP32 Core (GitHub) LuaNode for ESP32 (GitHub)
