Keyestudio ESP32-WROOM-32D Module Core Board /Wi-Fi+BT+BLE MCU

The Keyestudio ESP32-WROOM-32D Module Core Board is a highly integrated, mini development board designed for IoT projects, smart home automation, and wireless prototyping. It is an ideal choice for students, makers, and professional developers looking for a compact and powerful Wi-Fi and Bluetooth solution. With its dual-core processing and standard pin headers, it simplifies the transition from breadboard prototyping to final deployment.

Dual-mode wireless connectivity

This board features the industry-leading ESP-WROOM-32 module, combining Wi-Fi and dual-mode Bluetooth (v4.2 BR/EDR and BLE) on a single chip. It supports 802.11 b/g/n/e/i Wi-Fi protocols with speeds up to 150 Mbps, making it perfect for high-speed internet-of-things applications.

Breadboard-friendly pin layout

Most of the I/O ports are broken out to standard 2.54mm pitch pin headers on both sides of the board. This layout makes prototyping, debugging, and connecting external sensors or peripherals exceptionally straightforward.

Highly integrated RF architecture

The onboard ESP-WROOM-32 module integrates an antenna switch, RF balun, power amplifiers, low-noise amplifiers, filters, and power management modules. This design requires fewer than 10 external components, ensuring reliable radio frequency performance and a compact footprint.

Low-power silicon technology

Built using TSMC's low-power 40nm technology, the core processor delivers safe, reliable, and highly scalable performance. This makes it highly efficient for battery-powered or energy-conscious remote monitoring applications.

Robust onboard USB-to-serial interface

The board features an onboard CP2102-GMR USB-to-serial port chip for easy programming and debugging over a standard USB connection. It operates at a stable 5V DC voltage with an average operating current of 80mA and requires a minimum current supply of 500mA.
