ESP-WROOM-32 ESP-32S Development Board 30-Pin WiFi + Bluetooth with CP2102 & Type-C

• Module: ESP-WROOM-32 (ESP-32S)

• Processor: Dual-core Xtensa® 32-bit LX6 (up to 240MHz)

• USB Bridge: Silicon Labs CP2102 (Premium stability, no driver headaches)

• Connector: USB Type-C (Reversible and durable)

• Memory: 448 KB ROM, 520 KB SRAM, 4MB External Flash

• Connectivity: Wi-Fi 802.11 b/g/n + Bluetooth v4.2 BR/EDR & BLE

• Form Factor: 30-Pin (Breadboard-friendly narrow design)

• Operating Voltage: 3.3V (Logic), 5V (USB/Vin Input)

• Peripherals: 12-bit ADC, 8-bit DAC, SPI, I2C, I2S, UART, PWM, Capacitive Touch

Key Applications & Projects

• Smart Home Hubs: Create a secure gateway for Zigbee or BLE sensors.

• Industrial Data Loggers: Reliable high-speed serial logging via CP2102.

• Audio Over IP: Stream MP3 or AAC audio thanks to dual-core processing.

• BLE Mesh Networks: Deploy low-power sensor nodes in large environments.

Project Evolution

• Past Projects (Prerequisites): If you have worked with the basic ESP8266 or Arduino boards, you already know the basics of GPIO control.

• Feature Upgrade: This board unlocks True Parallel Processing. With two cores, you can dedicate one to heavy Wi-Fi/Cloud communication (like AWS or Firebase) while the second core handles real-time sensor interrupts without a single microsecond of lag.

• Effort Level: Intermediate. Works seamlessly with Arduino IDE, MicroPython, and ESP-IDF.

Virtual Technician & Wiring

Critical Warning: The CP2102 bridge handles data, but the board's logic is strictly 3.3V. Connecting 5V sensors directly to GPIO pins will result in permanent chip failure.

• Vin: Connect 5V external power here if not using USB.

• 3V3: Regulated output (Max ~500mA for peripherals).

• GPIO21 (SDA) / GPIO22 (SCL): Standard I2C pins.

• EN Button: Manual hardware reset.

Accessories

• Included: 1x ESP-WROOM-32 ESP-32S Development Board 30-Pin WiFi + Bluetooth with CP2102 & Type-C

• Required Additional: USB Type-C Data Cable, Breadboard for prototyping.
