The ADIY NodeMCU ESP32UE CP2102 is a powerful ESP32 development board built around the ESP32-WROOM-32UE module from DOIT. It combines Wi-Fi, Bluetooth, and BLE connectivity with a 32-bit dual-core MCU, manufactured using 40 nm ultra-low-power technology, delivering high performance with excellent energy efficiency.
This 30-pin NodeMCU board exposes most critical GPIOs and interfaces, enabling rapid prototyping and seamless integration into embedded designs. It features a Type-C USB connector, CP2102 USB-to-UART bridge, reset and boot buttons, and an onboard LDO regulator for stable power delivery.
A key advantage of the ESP32UE variant is the U.FL connector for an external antenna, allowing improved RF performance, extended wireless range, and flexible antenna placement—ideal for industrial, commercial, and long-range IoT deployments. The board also supports Arduino IDE, ESP-IDF, and Lua scripting, simplifying development for beginners and professionals alike.
