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.\u003c\/p\u003e\r\n\u003cp\u003e◆Three-in-One Multi-Functional for Multiple Communication Needs\u003c\/p\u003e\r\n\u003cp\u003eA 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.\u003c\/p\u003e\r\n\u003cp\u003e◆Wide Voltage Compatibility \u0026amp; Automatic RS485 Switching\u003c\/p\u003e\r\n\u003cp\u003eFeatures 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.\u003c\/p\u003e\r\n\u003cp\u003e◆High-Speed \u0026amp; Reliable Data Transmission\u003c\/p\u003e\r\n\u003cp\u003eDelivers 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.\u003c\/p\u003e\r\n\u003cp\u003e◆User-Friendly \u0026amp; Ready to Use\u003c\/p\u003e\r\n\u003cp\u003eDesigned for convenience with a reversible USB Type-C connector, an external 5V output (up to 300mA) to power connected devices, and included DuPont wires for immediate connection. Comprehensive tutorials and documentation are provided to help users get started quickly with various microcontrollers and industrial equipment.\u003c\/p\u003e\r\n\u003c\/div\u003e\n\u003cbutton class=\"expandable-content__toggle\" aria-expanded=\"false\" aria-controls=\"main-description\"\u003e\u003cspan class=\"expandable-content__toggle-icon\"\u003e\u003c\/span\u003e\u003cspan class=\"expandable-content__toggle-text\" data-view-more=\"View more\" data-view-less=\"View less\"\u003eView more\u003c\/span\u003e\u003c\/button\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"Yahboom","offers":[{"title":"Default Title","offer_id":46902840262807,"sku":"RM-YAHB-0JK","price":16.36,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/3997\/9927\/files\/912b4e5d_10.webp?v=1770635787","url":"https:\/\/ca.robotshop.com\/products\/yahboom-yahboom-usb-multi-functional-serial-port-module-separate-module","provider":"RobotShop Canada","version":"1.0","type":"link"}
