ESP 32 NODE MCU CP2102

The ESP32 NodeMCU (CP2102) is a dual-core Wi-Fi + Bluetooth/BLE development board based on the Espressif ESP32-WROOM module. Dual Xtensa LX6 CPU cores running at 80–240MHz, 520KB SRAM, 4MB Flash, and a rich peripheral set make it ideal for IoT, home automation, wearables, and multimedia applications. Ultra-low power: as little as 5µA in sleep mode. CP2102 USB-to-UART bridge for easy programming.
