QCCAN 8PCS TTL to RS485 - Review

Are you looking for a module that supports multi-machine communication and enables the conversion of TTL to RS485 or Serial UART? Then you might want to check out the QCCAN 8PCS TTL to RS485 Module. This module is designed for power supply and level mutual conversion for both 3.3V and 5V devices.

As a professional product reviewer, I've had the opportunity to test and examine this module and have come up with the following review.

Compatibility

First things first, the QCCAN 8PCS TTL to RS485 module is compatible with both 3.3V and 5.0V power and signals. So, regardless of the device you're using, this module promises smooth operation.

Indicator Lights

One notable feature of this module is its RXD and TXD signal indicator lights. These lights help you monitor the send and receive status of your device and give you a panoramic view of the system's performance. This feature, in my opinion, is quite useful and can come in handy when diagnosing issues.

Support for Multi-Machine Communication

Another exciting feature of the QCCAN 8PCS TTL to RS485 module is its support for multi-machine communication. You can connect up to 128 devices on the bus simultaneously, making it ideal for large-scale industrial projects. This feature means that you won't have to worry about the limited number of devices you can connect to your system.

Design

The QCCAN 8PCS TTL to RS485 module comes with a standard 2.54 pitch design, making it easier to set up and use. This design supports easy secondary development, enabling you to customize the module to fit your specific needs.

Matching Resistor

The 120 ohm matching resistor is another feature that sets the QCCAN 8PCS TTL to RS485 module apart from other modules. This matching resistor helps in long-distance transmissions, making it ideal for industrial applications. You can short-circuit R0 to activate the matching resistor for enhanced performance.
