ESP32 DevKit V1 — 30-Pin (Wi-Fi + Bluetooth, CP2102)

The ESP32 DevKit V1 is the go-to board for connected projects. Its ESP32-WROOM-32 module runs two 240 MHz cores with Wi-Fi and both classic Bluetooth and BLE, and the narrow 30-pin layout leaves a free row on each side of a standard breadboard. Plug it into USB, select "ESP32 Dev Module" in the Arduino IDE and you can host a web page, publish to MQTT or read sensors within minutes.

Key features

• ESP32-WROOM-32: dual-core 240 MHz, 520 KB SRAM, 4 MB flash
• Wi-Fi 802.11 b/g/n plus Bluetooth Classic and BLE 4.2
• CP2102 USB-to-UART with automatic boot/reset — no button pressing needed to upload
• 12-bit ADC, 2 DAC outputs, capacitive touch pins, PWM on every output pin
• 30-pin narrow layout that fits a single breadboard

Specifications

What's in the box

• 1 × ESP32 DevKit V1 30-pin board (headers soldered)

Ideal for

• Learning IoT and Wi-Fi programming
• Web-controlled relays and lights
• MQTT / Home Assistant sensors
• Bluetooth controllers

Good to know

• Install the CP2102 driver if your computer does not detect the board.
• ADC2 pins cannot be read while Wi-Fi is active — use ADC1 pins (GPIO 32–39) for analog sensors.
• USB connector (USB-C or Micro-USB) may vary by production batch.
