High-performance ESP32-WROOM-32 microcontroller with 30-pin layout and stable CP2102 USB driver. Integrated WiFi & Bluetooth for robust IoT applications.

Are your ideas outgrowing your hardware? If you have ever hit the memory limit on an Arduino Uno or felt the frustration of single-threaded blocking code freezing your robot, you are ready for the next level. The ESP32 30 Pin CP2102 Development Board is the answer to these "growing pains." It bridges the gap between simple hobbyist sketches and professional-grade IoT systems, offering a massive leap in processing power without forcing you to abandon the Arduino IDE ecosystem you already know.

Power meets versatility in a dual-core beast. Unlike standard 8-bit microcontrollers, this board features the Xtensa® Dual-Core 32-bit LX6 microprocessor running at up to 240 MHz. This allows you to delegate tasks—like maintaining a stable Wi-Fi connection on one core while reading sensitive sensors on the other—ensuring your projects run smoothly without crashes. With integrated Wi-Fi and dual-mode Bluetooth (Classic + BLE), it’s perfectly suited for everything from smart home energy monitors to app-controlled wearables.

Quality you can trust, priced for scale. At this aggressive price point, you might expect "bargain bin" quality, but we refuse to compromise. Every unit is Probots Lab Verified™ , meaning we test samples from each batch in our Bangalore facility to ensure the CP2102 USB driver negotiates data correctly and the antenna impedance is matched for reliable signal range. We source directly from Tier-1 factories to give you the Best Price Guarantee—eliminating the risk of receiving boards with bent pins or reject-grade silicon often found in generic marketplaces.

Built for safe and rapid development. We know that moving to 3.3V logic can be tricky, which is why we emphasize our Probots Logic-Safe™  protocols. We provide clear documentation to prevent you from accidentally frying your chip with 5V sensors. Coupled with our Probots Instant-R&D™  resources—including verified driver links and pinout charts available right on this page—you spend less time troubleshooting connections and more time building. This isn't just a component; it's a reliable platform for your long-term innovations.

Note:

  • The module previously referred to as "ESP32 WROOM-32" will now be primarily called ESP32.
  • This change is for naming consistency and does not affect the module's specifications, functionality, or physical characteristics.

Specifications:

  • Microcontroller: ESP-WROOM-32 
  • Clock Speed: Adjustable between 80 MHz and 240 MHz
  • Memory: 520 KB SRAM / 448 KB ROM / 4MB Flash
  • Wireless: 802.11 b/g/n Wi-Fi + Bluetooth 4.2 / BLE
  • Interface: CP2102 USB-to-UART Bridge (High Stability)
  • Pinout: 30 Pins (Breadboard compatible)
  • Logic Voltage: 3.3V (Not 5V tolerant)
  • Input Voltage: 5V via Micro USB 

Applications:

  • IoT Sensor Hubs: Collect temperature/humidity data and log it to Google Sheets.
  • Internet Radio: Stream MP3s utilizing high-speed Wi-Fi and I2S audio protocols.
  • Home Automation: Control AC mains appliances via relays with Alexa/Voice integration.
  • Low Power Wearables: Utilize BLE to send health data to smartphones.

The Project Evolution

  • Prerequisite (The Past): Mastery of Arduino Uno basics (loops, digital I/O).
  • The Upgrade (The Future): Unlocks FreeRTOS Multitasking. Run multiple loops simultaneously (e.g., blink an LED while waiting for a server response).
  • Effort Level: Intermediate. Requires 3.3V logic awareness.
  • Minimum Hardware: Micro USB Cable + Breadboard.

Virtual Technician & Wiring Guide
⚠️ CRITICAL: 3.3V Logic Warning Do NOT connect 5V sensors (like standard Ultrasonic sensors) directly to GPIO pins. Use a logic level converter or voltage divider.

  • Boot Mode: If upload fails, hold the "BOOT" button, press "EN", release "EN", then release "BOOT".
  • Pin Mapping: GPIO 2 is the Onboard LED.

Package includes:

1 X ESP32 30 Pin Development Board CP2102 WiFi + Bluetooth Dual Core IoT Module

Frequently Asked Questions (Technical FAQs)

  1. Why does my computer not recognize the ESP32 board?
    Ensure you are using a Data USB cable, not just a Charge cable. Also, install the Silicon Labs CP2102 VCP drivers.
  2. Does this board fit on a standard breadboard?
    Yes, the 30-pin version fits, but it leaves one row of holes accessible on only one side. For access to both sides, bridge two breadboards together.
  3. Can I power this board with a 9V battery?
    Yes, you can connect a 9V battery to the VIN pin and GND. The onboard regulator will step it down to 3.3V.
  4. Is the ESP32 5V tolerant?
    No. The GPIO pins are not 5V tolerant. Applying 5V directly to a pin will damage the ESP32.
  5. How do I put the board into Flash Mode?
    Usually, the CP2102 handles this. If upload fails, hold the "BOOT" button, press "EN" (Reset), release "EN", then release "BOOT".
  6. Does this board support MicroPython?
    Yes, the ESP32 is fully supported by MicroPython. You will need to flash the specific firmware first.
  7. What is the difference between the 30-pin and 38-pin versions?
    The 38-pin version simply breaks out a few more GPIO pins that are internally connected to flash memory (rarely usable). The 30-pin is more compact.
  8. Does it have built-in Bluetooth?
    Yes, it supports both Classic Bluetooth (BR/EDR) and Bluetooth Low Energy (BLE).
  9. Can I use the Arduino IDE to program this?
    Absolutely. You need to add the Espressif ESP32 URL to the "Additional Board Manager URLs" in preferences.
  10. How many Analog pins does it have?
    It has 18 Analog-to-Digital Converter (ADC) channels, though some are used by WiFi functionality.
  11. Why is the WiFi range poor?
    Ensure the PCB antenna area (the gold squiggly line at the top) hangs off the edge of your breadboard and isn't covered by metal.
  12. Can I use all pins for Input/Output?
    Not all. GPIO 34, 35, 36, and 39 are Input Only.
  13. What is the Brownout Detector error?
    This usually means your USB cable or power supply isn't providing enough current. Try a shorter, thicker USB cable.
  14. Does this have a battery connector?
    No, this specific dev board does not have a JST battery connector. Power via USB or VIN.
  15. Can it act as a Web Server?
    Yes, the ESP32 is powerful enough to host a simple website to display sensor data or control pins.
  16. How do I use the Touch Pins?
    Use the touchRead(pin) function in Arduino IDE. It returns a value changing based on capacitance (touch).
  17. Is the CP2102 better than CH340?
    Generally, yes. The CP2102 has higher data transfer rates and more stable driver support across different OS versions.
  18. Can I update the firmware over the air (OTA)?
    Yes, the ESP32 supports OTA updates, allowing you to upload code wirelessly.
  19. Does it support deep sleep?
    Yes, it has excellent deep sleep modes, consuming roughly 10 µA, making it great for battery projects.
  20. What is the maximum current per GPIO pin?
    It is recommended to draw no more than 12mA per pin, with a maximum absolute limit of 40mA.
