Product Description The ESP32 CP2102 30-Pin Development Board is a powerful, dual-core system-on-chip (SoC) designed for advanced IoT applications and wireless prototyping. This version features the modern Type-C USB interface for improved durability and faster data transfer, paired with the highly stable CP2102 USB-to-Serial bridge for seamless programming. With its integrated 2.4 GHz dual-mode WiFi and Bluetooth (Classic and BLE), this board is capable of handling complex tasks ranging from low-power sensor networks to heavy-duty web servers and voice encoding. Its 30-pin narrow form factor is specifically chosen to ensure it fits perfectly on a standard breadboard while leaving rows free for easy jumper wire connections.

Key Features

  • Dual-Core Processing: Powered by two Xtensa® 32-bit LX6 microprocessors, allowing one core to handle wireless stacks while the other runs your application code.

  • Modern Type-C Port: Upgraded from Micro-USB to Type-C for a more robust physical connection and universal cable compatibility.

  • Hybrid Connectivity: Supports both high-speed 802.11 b/g/n WiFi and Dual-Mode Bluetooth (v4.2 BR/EDR and BLE) for versatile communication.

  • CP2102 Serial Bridge: Features the industry-standard Silicon Labs CP2102 IC, known for its superior driver stability and high-speed flashing capabilities.

  • Breadboard Friendly: Optimized 30-pin width allows the board to be plugged into a breadboard with one row of pins accessible on each side.

Technical Details

  • Processor Architecture: 32-bit dual-core processor operating at a tunable frequency from 80 MHz to 240 MHz.

  • Ultra-Low Power Co-processor: Includes an independent ULP co-processor for monitoring GPIOs or internal sensors while the main cores are in deep sleep.

  • Advanced Peripherals: Integrated capacitive touch sensors, Hall sensors, SD card interface, high-speed SPI, I2S, I2C, and UART hardware.

  • Security Suite: Features hardware-accelerated encryption including AES, SHA-2, RSA, ECC, and a Random Number Generator (RNG).

  • Deep Sleep Efficiency: Consumes as little as 10µA in deep sleep mode, making it ideal for battery-operated remote sensor nodes.

  • Power Management: Onboard AMS1117 3.3V regulator handles the current surges required during WiFi transmission bursts (up to 500mA).

  • Memory Architecture: 448 KB of ROM for booting and core functions, alongside 520 KB of internal SRAM for data and instructions.

  • External Flash: Equipped with 4MB of external SPI Flash memory to store large programs, file systems (SPIFFS/LittleFS), and web assets.

  • PWM Channels: 16 independent LED PWM channels with high-resolution control, perfect for motor drivers and RGB lighting.

  • ADC and DAC: 12-bit Analog-to-Digital Converter across multiple channels and two 8-bit Digital-to-Analog Converter channels.

  • Antenna Design: Features a high-performance PCB trace antenna for reliable wireless range without external hardware.

  • Input Voltage Flexibility: Can be powered via the 5V Type-C port, the Vin pin (5V-12V), or directly through the 3.3V pin (regulated).

  • Firmware Support: Fully compatible with Arduino IDE, MicroPython, Espressif IoT Development Framework (ESP-IDF), and Lua.

  • Logic Level: Operates strictly on 3.3V logic; level shifters are required when interfacing with 5V sensors or displays.

  • OTA Updates: Supports Over-The-Air (OTA) firmware updates, allowing you to reprogram the board remotely over WiFi.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: You can power the ESP32 through the Vin pin using a 9V battery. However, since the ESP32 consumes significant power during WiFi peaks, a small 9V battery will drain quickly. For stable IoT projects, we recommend a 9V 2A DC Adapter.

  • 18650 Cell: The most efficient way to power this board for portable use is using a Single 18650 Cell (3.7V) connected to a TP4056 charging module with a 5V boost converter feeding the Vin pin.

  • IC & Capacitor Tip: If you experience random "Brownout" resets during WiFi connection, add a 1000uF 10V Electrolytic Capacitor across the 3.3V and GND pins. This provides a reservoir of current to handle sudden wireless transmission spikes.

  • Related Products: We recommend pairing this with our DHT22 Temperature Sensors, 0.96 inch I2C OLED Displays, and 3.7V 18650 High-Discharge Cells.
