SazkJere Access-Control Keypads Editorial Review
The four-pack of 3x4 matrix keypad modules has garnered mixed reviews from customers, highlighting both functionality and significant drawbacks. Users appreciate the overall design's suitability for embedded projects, emphasizing that the welded headers simplify assembly and allow for easy integration with microcontrollers that can manage row and column scanning. However, numerous complaints arise around the lack of documentation included in the package. Many customers noted that while the essential pin mapping information was available online, the absence of a physical reference makes initial setup frustrating and complicates troubleshooting. Additionally, while the Construction is generally functional, users pointed out that the arrangement of the pins could be misleading, as two of them are non-functional, and the right-angle setup takes up more space than necessary. This could deter those without a strong background in electronics, particularly when trying to decode outputs. Although the pricing at $16 for four keypads seems reasonable, customers feel that better alternatives exist in the market that offer clearer documentation and easier integration options, like I2C adapters. Overall, while the product serves its purpose, it may not be the best choice for everyone, particularly those new to working with keypads. **
