Key features and benefits - Isolated USB TTL converter with TYPE-C interface for easy connection to a computer. Plug in a TYPE-C data cable to connect. - Signal sampling uses a dedicated signal isolation chip, providing a more stable output. - Clear power indicator and humidity module indicators improve visibility and troubleshooting. - USB power supply: 5V via TYPE-C interface. - TTL end signal level: 3.3V. The TTL end only supports 3.3V power supply and 3.3V TTL signal, not 5V. - TTL terminal power supply: 3.3V, with a power indicator. Compatibility and performance - Suitable for 3.3V TTL devices and systems that require isolated USB serial communication. - Isolation helps protect both the PC and the connected hardware from ground loops and electrical noise, improving reliability in development and testing environments. - Clear indication of power status aids in quick setup and troubleshooting. Technical details at a glance - Interface: TYPE-C for USB connection - Power supply: USB 5V (TYPE-C) - TTL end signal level: 3.3V - TTL terminal power supply: 3.3V - Indicators: power indicator and humidity module indicators Use scenarios - Microcontroller development and programming: Connect a 3.3V MCU (such as ESP32, STM32, or similar) to a PC for programming, debugging, and data logging using a stable, isolated serial link. - Sensor data collection and hardware debugging: Interface 3.3V TTL sensors or modules to a computer for data capture, monitoring, and troubleshooting with reduced electrical noise and better signal integrity. - 3.3V serial communications in test benches: Use in lab setups where isolated USB TTL communication to 3.3V devices is required for safe testing and quick iteration.
