ESP32 30-Pin Development Board CP2102 WiFi Bluetooth
ESP32 30 Pin CP2102 Development Board with Wi-Fi and Bluetooth
The ESP32 30-pin development board with CP2102 USB‑UART chip integrates 2.4 GHz Wi‑Fi and Bluetooth 4.2/5.0. It is built for IoT prototypes, sensor networks, and low‑power applications that need reliable wireless connectivity. A dual‑core Tensilica LX6 processor drives this compact board, giving makers a ready‑to‑use platform for connected projects.

Compatibility
Works with Arduino IDE, PlatformIO, and Espressif IDF. Designed for 3.3 V logic sensors (DHT22, OLED, relay modules). Onboard 3.3 V regulator delivers up to 600 mA for external circuits. Standard pin‑spacing fits breadboards and common shields.
Wiring Notes
Always power peripherals from the 3.3 V pin. A single GPIO can source 40 mA, but keep the total draw under the regulator limit. Default serial pins are TX (GPIO1) and RX (GPIO3); avoid loading them during upload.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino IDE?
Yes. Install the ESP32 board package via Boards Manager, select “ESP32 Dev Module”, and choose the appropriate partition scheme. The CP2102 driver must be installed on your computer for uploading code.
Can I power this board with a 18650 battery?
The board runs on 3.3 V logic but needs a regulated 5 V supply. A 3.7 V 18650 cell can be boosted to 5 V with a step‑up module and connected to the 5 V pin. Direct connection to 3.3 V may cause brown‑outs.
What comes inside the box?
You receive the ESP32 development board only. No USB cable, headers, or sensors are included.
📦 Free Setup Handoff Document Included
Every Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes. Download it via QR code on your package. The handoff document is also trained to help you troubleshoot the majority of problems.
