Hw-597 Driver Guide
Cause: Trying to install 32-bit driver on 64-bit Windows, or vice versa.
Fix: Download the latest CH341SER.EXE which includes both architectures.
Unlike simple LED modules, the HW-597's inputs are inverted.
Why?
The module uses an NPN transistor (e.g., S8050) with a pull-up resistor. Driving the input pin LOW turns the transistor ON, activating the relay.
The HW-597 is not a unique chip; it is a breakout board that typically uses one of two popular chipsets:
Identifying the correct chipset is step one. Look at the main black IC on the HW-597 board. If it says “CH340G” or “CH341A,” you need the CH340 driver. If it says “PL2303,” you need the Prolific driver.
Note: The HW-597 is frequently confused with the HW-597 ESP8266 adapter or the HW-597 serial programmer. All refer to the same driver logic.
Because the logic is inverted, you write LOW to turn the relay on.
// HW-597 Dual Relay Module - Active LOW Driver #define RELAY1 4 #define RELAY2 5void setup() pinMode(RELAY1, OUTPUT); pinMode(RELAY2, OUTPUT);
// Initialize both relays OFF (HIGH = de-energized) digitalWrite(RELAY1, HIGH); digitalWrite(RELAY2, HIGH);
void loop() // Turn Relay 1 ON (Active LOW) digitalWrite(RELAY1, LOW); delay(1000);
// Turn Relay 1 OFF digitalWrite(RELAY1, HIGH); delay(1000);
// Turn Relay 2 ON digitalWrite(RELAY2, LOW); delay(1000); hw-597 driver
// Turn Relay 2 OFF digitalWrite(RELAY2, HIGH); delay(1000);

Disclaimer: HW-597 is a hardware identifier, not a chipset. Always identify the IC on your specific board.
The HW-597 USB to TTL Converter Module is a widely used, low-cost adapter based on the CH340G chip. It serves as a bridge for connecting microcontrollers (like Arduino Pro Mini, ESP8266, or ESP32) and other serial-based hardware to a computer via USB. Performance Review
Reliability: Based on expert feedback and user reports, the CH340G chip is a highly stable and cost-effective alternative to more expensive FTDI chips. It is generally more resilient against driver-related "bricking" issues often seen with non-genuine FTDI chips during Windows updates.
Compatibility: It works seamlessly across Windows (XP through Win10/11), Linux, and macOS. While newer macOS versions like Mojave often include the drivers natively, some users on different Mac configurations report occasional driver instability.
Ease of Use: The board features onboard LED indicators for Power (PWR), Transmit (TXD), and Receive (RXD), which provide instant visual feedback on data activity without needing external diagnostic tools. Key Features & Specifications
Dual Voltage Support: It includes a jumper for easy switching between 3.3V and 5V logic levels, making it versatile for various DIY electronics.
Data Speed: Supports a wide range of baud rates from 50 bps up to 2 Mbps.
Build Quality: Often features high-quality "yellow pins" that are noted for being more durable than standard black pins found on some budget clones. Cause: Trying to install 32-bit driver on 64-bit
Compact Form Factor: The module measures approximately 55mm x 16mm, making it easy to integrate into tight project spaces. Limitations to Consider CH340 USB to TTL (Serial) HW 597 Converter Module
