Velleman Access-Control Keypads Editorial Review

Velleman 12 Key Keyboard - Common Output - Blister-Packed is a retro-styled keypad ideal for projects involving microcontrollers like Arduino. It features a layout reminiscent of antique phone buttons, making it not only functional but also visually appealing. This keypad has a common output, with a COM terminal to connect to the ground and individual pins for each button, which requires you to manage your connections carefully as it demands 10 digital inputs. While some users appreciate its ease of use, soldering headers or wires onto the terminals is necessary, adding a learning opportunity for those without soldering experience. This lightweight keypad is well-suited for testing and prototyping, though some users have expressed concerns about its long-term durability.
