: Standard connections include VCC , GND , TXD , RXD , and often DTR (for auto-resetting Arduinos during programming).
Manufactured by FTDI. (Note: Budget HW-417 boards often feature counterfeit FTDI chips that require older, specific drivers to bypass manufacturer blocks). PL2303: Manufactured by Prolific. 📥 Driver Download and Installation Guide
Open the (Right-click Start > Device Manager). Expand the Ports (COM & LPT) section.
As with all driver-related tasks, your first stop should always be the hardware manufacturer's official website (for the FTDI chip, that's ). Avoid generic driver-updater software from unknown sources. hw-417-v1.2 driver
The is a high-performance USB-to-Serial converter board designed to provide a stable, high-speed data link between a modern PC (USB interface) and legacy or industrial hardware (Serial/UART interface). Version 1.2 introduces improved voltage regulation and ESD protection compared to earlier revisions.
The HW-417 v1.2 module operates by mimicking a traditional legacy RS-232 serial hardware infrastructure through a computer's modern USB port. Drivers - FTDI
Ensure the voltage jumper (3.3V vs 5V) matches your microcontroller's requirements to avoid hardware damage. : Standard connections include VCC , GND ,
:
Identifying your specific HW-417-V1.2 is the first step to finding the correct driver. The term "driver" here is used loosely—it could mean a Linux kernel module, a Python library, or a communication protocol.
If you want, I can:
: If the module is not recognized as "FTDI" in your Device Manager, you may need the CH340 drivers from WCH . Technical Specifications
and look under "Ports (COM & LPT)." You should see an entry like "USB Serial Port (COMx)". Critical Troubleshooting for HW-417 "Fake" Chips
| Problem | Likely Fix | |--------|-------------| | Device not detected | Try another USB cable/port, reinstall driver | | Driver install fails (Windows) | Disable driver signature enforcement temporarily (Windows 10/11) | | Garbled serial data | Check baud rate matching, ground connection | | Device shows but can’t open | Close other serial programs, check permissions (Linux: sudo chmod 666 /dev/ttyUSB0 ) | PL2303: Manufactured by Prolific
