Product Description

The ESP32 30-Pin Board is the successor to the ESP8266, offering significantly more processing power and a much richer set of sensors and communication ports. It features an integrated CP2102 or CH340 USB-to-Serial converter (depending on the specific variant) for easy programming via the Arduino IDE, MicroPython, or Espressif IDF. The board includes onboard power management, a PCB antenna, and dual buttons for Reset (EN) and Boot, making it a self-contained unit for rapid prototyping.

Key Features

  • Dual-Core Processing: Allows you to run WiFi/Bluetooth stacks on one core while executing your time-critical application code on the second core.

  • Hybrid Connectivity: Simultaneously supports WiFi for cloud communication and Bluetooth for local smartphone interaction or low-energy beaconing.

  • Rich Peripheral Set: Includes capacitive touch sensors, Hall effect sensors, and an internal temperature sensor for built-in environmental awareness.

  • Ultra-Low Power: Consumes less than 5µA in deep sleep, making it ideal for battery-operated wearables and remote sensor hubs.

  • Breadboard Friendly: This 30-pin version is narrower than the 38-pin version, ensuring you have at least one row of usable pins on a standard breadboard.

Technical Details

  • Dimensions: ~48mm x 28mm (fits standard breadboards).

  • Security: Hardware-accelerated AES, SHA-2, RSA, and ECC.

  • Software: Supports Lua, Arduino C++, MicroPython, and CircuitPython.

Prototyping and Engineering Tips from Robogears

  • The 3.3V Logic Rule: The ESP32 operates at 3.3V. Connecting a 5V signal to any GPIO pin can permanently damage the chip. Use a Bi-Directional Logic Level Converter when working with 5V sensors.

  • Power-Hungry WiFi: During WiFi transmission, the ESP32 can draw up to 500mA. If your board resets randomly, it is likely due to a weak USB port or a poor-quality USB cable. Use a high-quality cable or power it via a dedicated 5V/1A supply on the VIN pin.

  • Boot Button Usage: If the Arduino IDE fails to upload code, hold down the BOOT button, start the upload, and release it when "Connecting..." appears in the console.

  • Analog Pin Caution (ADC2): Avoid using ADC2 pins (GPIOs 0, 2, 4, 12, 13, 14, 15, 25, 26, 27) if your project uses WiFi simultaneously, as the WiFi driver uses the same internal hardware. Stick to ADC1 pins (GPIOs 32–39) for stable analog readings while connected.

Package Includes

  • 1 x ESP32-WROOM-32 WiFi + Bluetooth Development Board (30-Pin)
