ESP-32S NodeMcu CH340 38Pin Development Board

ESP-32S NodeMcu CH340 38Pin Development Board is a compact development board designed for hardware prototyping and firmware development. The board measures 25.5 mm in width and is explicitly designed to mount on standard solderless breadboards, providing a convenient form factor for quick circuit assembly and testing.Featuring a 38-pin layout, this module exposes a range of I/O connections suitable for connecting sensors, actuators, and peripheral modules during development. The board integrates a CH340 USB-to-serial interface for easy connection to a host computer, enabling straightforward serial communication and firmware flashing through common development toolchains that support USB serial adapters.Its NodeMcu-style footprint and header arrangement make it suitable for iterative prototyping, educational projects, and proof-of-concept builds where a small, breadboard-compatible development board is required. The compact width and pin spacing are optimized for clean placement on prototyping boards, minimizing the need for additional wiring and adapters.This product is ideal for developers and hobbyists who require a breadboard-friendly development board with a CH340 USB interface and a 38-pin configuration.
