KNACRO RS485 to TTL UART - Review

When it comes to communication data protocols, writing programs for 485 flow control can be a challenging and daunting task. This is especially true when dealing with unknown data protocols, where you're not sure when to switch the directions for receiving and sending data. Fortunately, KNACRO has developed a solution to these problems with their 485 automatic flow control module.

The KNACRO RS485 to TTL UART MCU Serial Port Signal Mutual Conversion Module is an optocoupler isolated and over-current anti-reverse protection communication module that is designed to make 485 flow control much easier. The product features an integrated automatic transceiver 485 industrial grade chip, which enables ultra-long-distance transmission up to kilometers. Additionally, the module features positive and negative 15KV ESD protection, further enhancing its durability in different environments.

One standout feature of this product is the chip's slew-rate-limited driver. This driver effectively reduces EMI and signal reflections that may result from improperly terminated cables. As a result, users can enjoy error-free signal transfer rates up to 500Kbps. This reliable data transmission capability, combined with the optocoupler isolation protection, ensures that data is transmitted securely and with little to no interference.

The KNACRO RS485 to TTL UART MCU Serial Port Signal Mutual Conversion Module is also highly compatible with multi-machine communication, allowing access to up to 128 devices on the bus. The product stands out with its 1/4 unit load receiver input impedance, which makes it suitable for communication with a wide range of devices. Users can also enjoy industrial chip operating temperatures of up to -40 ℃ to +85 ℃, making it perfect for use in various industrial applications.

One other remarkable feature of the module is that it can be hot-swappable, without causing other 485 chip hot plug signals to fail. Additionally, the dual transient suppression diodes in the product provide superior overvoltage protection, adding to the safety and security of the module during use.

While the product does bring a lot of benefits to the table, it's not without some negative feedback from customers. Currently, the KNACRO RS485 to TTL UART MCU Serial Port Signal Mutual Conversion Module only has one customer review, which gives the product a 1.0 out of 5 stars rating. The low rating may discourage potential buyers, but it's important to note that one review does not represent the entire product's experience with customers.

In summary, KNACRO RS485 to TTL UART MCU Serial Port Signal Mutual Conversion Module is an essential tool for any professional dealing with communication data protocols. The product's features, including the optocoupler isolation protection, over-current anti-reverse protection, and multi-machine communication compatibility make it an ideal choice for different industrial applications. With its ultra-long-range transmission capability, this 485 automatic flow control module is a reliable investment that can offer durable and secure data transmission, even in harsh environments. However, potential buyers should note that one review may not be enough to make a definitive purchasing decision.
