ESP32 CP2102 Type-B Development Board NodeMCU ESP-WROOM-32 WiFi Bluetooth Module

The ESP32 CP2102 Type-B Development Board is a feature-rich, dual-core microcontroller platform designed to serve as a robust, low-power core for advanced Internet of Things (IoT) applications, web hosting, and automation networks. At its heart lies the industry-vetted ESP-WROOM-32 module, housing an Xtensa® 32-bit LX6 dual-core processor that clocks up to 240MHz. By combining 520KB of internal SRAM, 448KB of ROM, and 4MB of high-speed onboard SPI Flash, this micro-controller easily manages multitasking, processes complex multi-sensor calculations, and operates standalone wireless environments with exceptional efficiency.

This board utilizes a classic, structurally reinforced Micro-USB (Type-B) interface alongside the premium Silicon Labs CP2102 USB-to-UART bridge chip. This setup delivers steady data transmission pipelines and automatic bootloader entry for painless code uploading in the Arduino IDE, ESP-IDF, or MicroPython environments. On the wireless front, it delivers 2.4GHz dual-mode Wi-Fi and Bluetooth connectivity backed by a full LWIP stack and real-time FreeRTOS scheduling. The module supports three distinct network operating modes: Station mode (STA) to link with existing Wi-Fi routers, Access Point mode (AP) to host its own localized network, and hybrid AP+STA mode for simultaneous local bridging and external data streaming. Built on an expanded 38-pin breadboard-friendly layout with tactile Enable (EN) and Boot switches, it serves as an excellent hardware foundation for building smart security nodes, localized web servers, custom robotic interfaces, and complex embedded machinery.
