ESP32 NodeMCU Development Board with ESP-WROOM-32 38-pin USB-C

Advanced NodeMCU development module based on the popular ESP-WROOM-32 chip. The board is equipped with a modern USB-C connector and a reliable CP2102 USB-UART converter, making programming and communication easy. The module is built on a powerful 32-bit dual-core architecture, offering high computing power for demanding IoT applications. Thanks to the optimal pin row spacing (22.5 mm), when mounted on a breadboard, one row of sockets remains free on both sides of the module, providing convenient access to all pins. The product is fully compatible with the Arduino IDE environment for ESP32, for Arduino, and other popular development platforms.
