QCCAN Single Board Computers Editorial Review

The 4PCS PCF8575 IO Expander Module has garnered mixed reviews from customers, reflecting both its potential and its drawbacks. Many users appreciate the functionality that these modules offer in expanding the I/O capabilities of their projects. However, a common theme among the reviews is the need for caution when handling these boards. One critical point mentioned is the necessity of soldering the A0, A1, and A2 pins to set the I2C address. This step is crucial; otherwise, users may face unexpected changes in the address during operation, which could lead to troubleshooting confusion. Additionally, the pin numbering on the boards presents a challenge, as the silk-screened labels skip certain numbers, causing further potential misunderstanding in code execution. While the boards are generally functional, customer experiences varied regarding their quality. A few users encountered non-functional boards, raising concerns about the reliability of the modules. This unpredictability can hamper projects, especially for those who intended to utilize multiple boards simultaneously. In some cases, users had to resort to painstaking troubleshooting only to discover that the fault lay with the hardware itself rather than their coding or wiring efforts. Overall, the 4PCS PCF8575 IO Expander Module is presented as a cost-effective solution for those adept at soldering and troubleshooting hardware but poses a risk of receiving defective units. **
