ESP-WROOM-32 WIFI Bluetooth

ESP-WROOM-32 Wi-Fi & Bluetooth Module
If you’re moving past breadboards and starting to design your own custom circuits or permanent IoT products, the ESP-WROOM-32 is what you’re looking for. It’s designed for everything from simple battery-powered sensors to heavy-duty tasks like audio streaming and real-time data processing.

Why it’s a professional choice:
• Dual-Core Power: It features two CPU cores with adjustable speeds (80 MHz to 240 MHz). This means one core can handle your Wi-Fi connection while the other runs your complex code, so nothing ever lags.
• Master of Wireless: It supports Wi-Fi for long-range internet access and Bluetooth/BLE for talking to smartphones or acting as a beacon. With a massive 22 dBm output power, it has an impressive wireless reach.
• Ultra-Low Power: This module is a king of efficiency. In "deep sleep," it draws as little as 5µA, making it the perfect choice for wearables or remote sensors that need to run on a single battery for months.

Packed with Features:
• Built-in Sensors: You get integrated capacitive touch sensors, a Hall Effect sensor (for magnets), and even low-noise amplifiers.
• High-Speed Connectivity: It’s ready for anything with SDIO/SPI, UART, and I²C interfaces. It even supports data rates up to 150 Mbps for fast communication.
• Onboard Flash: The module comes with integrated flash memory, so your code and data are stored safely right on the chip.

Best For:
This module is the "gold standard" for IoT systems, smart home devices, and wireless audio projects. It’s the go-to component when you need maximum performance and connectivity in the smallest possible space.
