The ESP32 CH340C Type‑C development board is a versatile Wi‑Fi + Bluetooth solution for makers, students and professionals in Bangladesh. Powered by the ESP32 dual‑core 32‑bit microcontroller, this board gives you high processing power, integrated wireless connectivity and rich peripherals in a compact, breadboard‑friendly package.

A built‑in CH340C USB‑to‑serial converter ensures stable programming and serial communication over a USB Type‑C connector. You can upload code directly from the Arduino IDE, PlatformIO or ESP‑IDF without extra hardware. Auto‑reset/auto‑download circuitry means you usually don’t need to press BOOT/RESET buttons during flashing.

With integrated 2.4 GHz Wi‑Fi (802.11 b/g/n) and Bluetooth (BR/EDR + BLE), this ESP32 board is an excellent choice for:

• IoT and smart home devices
• Wireless sensor networks
• Home automation and monitoring
• Robotics and RC projects
• Embedded systems learning and university projects

Buy the ESP32 CH340C Type‑C development board from BD Electronics (bdelectronics.xyz) and get a reliable platform for your next connected project anywhere in Bangladesh.
