Connect the TXD pin to the RXD pin on the HW-597 using a jumper wire. Open a serial monitor (PuTTY, Screen, or Arduino Serial Monitor). Send a character. If you receive the same character back, the driver and hardware are working perfectly.

The room smelled of coffee and warm plastic. On the table lay the laptop — its screen cracked like a dried riverbed — and, beside it, a USB stick labeled with a sliver of grease: hw-597-driver.bin.

You plug it in. The LED blinks a patient morse. Lines of code crawl into view, each function a practiced breath.

Example (imagined excerpt):

Understanding the hardware helps when troubleshooting driver behavior. The HW-597 exposes six pins:

Important: The HW-597 operates at either 5V or 3.3V logic levels. Ensure your target device matches the voltage. Failure to do so can damage the device or the HW-597.
