This USBC to Serial Port UART Board Module provides a galvanically isolated USBtoTTL interface at 3.3V with a TypeC connector. Designed for modern hosts and embedded targets, it offers a compact, reliable way to connect a USBC computer or device to TTLlevel serial equipment while protecting both sides from electrical noise and ground loops. Key benefits Isolated USBtoTTL communication: galvanic isolation helps protect your computer and your target device in industrial or lab environments. 3.3V TTL compatibility: suitable for many microcontrollers and sensors that operate at 3.3V, reducing risk of voltage damage. USBC interface for broad compatibility: works with USBC hosts and devices, including newer laptops and SBCs. Simple Arduino/MCU debugging and programming aid: convenient for firmware updates, bootloader access, and serial monitoring. Industrialready design: packaged as a compact, singleboard module in black for durable, fielduse applications. One piece per package: convenient for kits and production setups. Key attributes Functionality: USBC to Serial Port UART board with isolated USBtoTTL capability. Compatibility: supports 3.3V TTL devices; compatible with USBC hosts. Interface: USBC connector for host connection; TTL UART for device connection. Voltage: 3.3V logic level. Color/appearance: Black. Packaging: 1 piece per . Build context: Industrialgrade styling suitable for workshop and lab use. Essential note: The description reflects the product's stated features including isolation, USBC interface, 3.3V TTL level, and TypeC connectivity. Two to three use cases Microcontroller programming and flashing: connect the USBC host to the UART pins of 3.3V MCU boards (such as ESP32/STM32/Arduinofamily) for bootloader access and firmware uploads. Serial console and debugging: use the USBC host to access the device's serial console for realtime logging, debugging, and sensor data monitoring in development or maintenance tasks. Firmware updates in industrial settings: employ the isolated USBtoTTL link to safely update firmware on field devices or test rigs without risking ground loops or voltage conflicts with industrial equipment. How to use (quick guide) Connect the USBC end to your USBC host (PC, laptop, or SBC). Connect your 3.3V TTL device to the UART pins on the module (respect 3.3V logic and ground references). Power the setup as required by your host and target. Use your preferred serial software to communicate at the appropriate baud rate and settings for your device.
