Description
PCB FOR ESP32-S3 USB Development Board
Product Description
This product is a high-quality empty bare PCB designed for the ESP32-S3 module, intended for DIY assembly, prototyping, and custom embedded development.
The board integrates a CH340C USB-to-UART interface combined with a UMH3N transistor array to provide fully automatic serial uploading and programming, eliminating the need for manual BOOT or RESET button handling.
It features dual USB Type-C connectors, each protected by a USBLC6 ESD protection chip, ensuring enhanced durability and protection against electrostatic discharge during development and frequent connections.
An onboard WS2812 RGB LED allows user-programmable visual feedback for system status, debugging, or UI indicators.
This product is sold as an empty bare PCB, giving makers full flexibility to choose components and assemble according to their project needs. A soldering and assembly guide is provided for easy construction.
