ESP32-WROOM-32 Dev Board WiFi Bluetooth

This development board features the ESP32-WROOM-32 module, built on a PCB substrate. It measures standard ESP32 dev board dimensions (approximately 52.5 × 26.5 mm) and weighs around 10 g. The board integrates dual-mode wireless connectivity — 2.4 GHz WiFi (802.11 b/g/n) and Bluetooth 4.2 BR/EDR & BLE. It is powered via micro-USB using the CP2102 USB-to-serial chip for reliable programming and serial communication. Designed for prototyping and small-batch deployment, it supports Arduino IDE, ESP-IDF, MicroPython and PlatformIO. The black PCB has standard pin headers (male or female depending on batch), with no integrated sensors or additional peripherals beyond the core ESP32-WROOM-32 module and CP2102 interface. The board delivers stable wireless performance for embedded IoT firmware development, including over-the-air (OTA) updates, low-power sleep modes, and GPIO-rich interfacing (34 digital I/O pins, multiple ADC/DAC, PWM, I²C, SPI, UART). Its compact form factor and native support for both WiFi and Bluetooth make it suitable for smart home controllers, sensor nodes, remote actuators and mobile-connected edge devices. Use cases include DIY home automation hubs, BLE-enabled environmental monitors, WiFi-connected door/window sensors, OTA-updatable firmware prototypes, and educational IoT projects requiring dual-radio wireless integration.
