YAHBOOM USB Multi-Protocol Serial Converter Module For STM32, ESP32, RPi, Spec: Module


1. The Yahboom USB Multi-Function Serial Module is a powerful, high-performance serial communication tool designed to simplify and accelerate embedded development and industrial debugging. It integrates three essential conversion modes onto a compact circuit board: USB-to-TTL, USB-to-RS485, and TTL-to-RS485, eliminating the need for multiple adapters. The module supports 1.8V/3.3V/5V TTL level switching, RS485 hardware automatic direction switching circuitry, and supports high-speed transmission up to 6 Mbps (TTL) and 12 Mbps (RS485), ensuring broad compatibility, reliable data transmission, and a simplified workflow for applications involving STM32, ESP32, Raspberry Pi, Jetson, RDK, and industrial PLCs.
2. Tri-function Module: A single module replaces three separate adapters, supporting USB-to-TTL (for programming and debugging), USB-to-RS485 (for PC-to-industrial equipment communication), and TTL-to-RS485 (for microcontroller-to-industrial network connection). An onboard DIP switch enables quick, tool-free mode selection, saving time and reducing hardware redundancy.
3. Wide Voltage Compatibility & RS485 Auto-Direction: Features a selectable TTL voltage switch (1.8V/3.3V/5V) for safe connection to low-power chips, common MCUs, and Single Board Computers (SBCs) like Raspberry Pi and Jetson. Its built-in hardware circuitry automatically handles RS485 transmit/receive direction switching, eliminating complex software timing control and preventing data loss in communication with industrial sensors, PLCs, or robotic bases.
4. High-Speed & Reliable Data Transmission: Supports TTL baud rates up to 6 Mbps and RS485 baud rates up to 12 Mbps with stable and reliable performance. Built-in professional TTL hardware flow control (RTS/CTS) prevents buffer overflow during high-speed data exchange. Onboard TVS and ESD protection, along with clear TX/RX/power indicators, ensure stable operation in electrically noisy environments.
5. Plug-and-Play: Designed for convenience, featuring a reversible USB Type-C connector, an external 5V output (up to 300mA) capable of powering connected devices, and included Dupont wires for quick user connections. Comprehensive tutorials and documentation are also provided to help users get started quickly with various microcontrollers and industrial equipment.

Parameters:
1. Main Chips: CH343P, SP3485EN-MS
2. Interface Type: USB Type-C (supports reversible insertion)
3. Communication Protocol: TTL (UART) / RS485
