Description

Tutorials: Serial communication module Yahboom USB Multi-functional Serial Port Module is a powerful and high-performance serial communication tool designed to simplify and accelerate embedded development and industrial debugging. It integrates three essential conversion modes into one compact board: USB to TTL, USB to RS485 and TTL to RS485, eliminating the need for multiple adapters. With support for 1.8V/3.3V/5V TTL level switching, RS485 hardware automatic direction switching circuit and high-speed operation up to 6Mbps (TTL) and 12Mbps (RS485), it ensures broad compatibility, reliable data transmission and a streamlined workflow for STM32, ESP32, Raspberry Pi, Jetson, RDK, and industrial PLC applications. Three-in-One Multi-Functional for Multiple Communication Needs A single module replaces three separate adapters by supporting USB to TTL (for programming and debugging), USB to RS485 (for PC-to-industrial device communication), and TTL to RS485 (for microcontroller-to-industrial network connection). An onboard DIP switch allows quick and tool-free mode selection, saving time and reducing hardware clutter. Wide Voltage Compatibility & Automatic RS485 Switching Features a selectable TTL voltage switch (1.8V/3.3V/5V) to safely interface with low-power chips, common MCUs, and SBCs like Raspberry Pi and Jetson. Its built-in hardware circuit automatically handles RS485 transmit/receive direction switching, eliminating complex software timing control and preventing data loss in industrial sensor, PLC, or robotic chassis communication. High-Speed & Reliable Data Transmission Delivers stable performance with TTL baud rates up to 6Mbps and RS485 rates up to 12Mbps. Includes professional TTL hardware flow control (RTS/CTS) to prevent buffer overflow during high-speed data exchange. Onboard TVS and ESD protection, along with clear TX/RX/Power LEDs, ensures robust operation in electrically noisy environments. User-Friendly & Ready to Use Designed for convenience with a rev
