Yahboom USB Multi-functional Serial Port Module for STM32, ESP32, RPi, Jetson, RDK

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 NeedsA 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
