Customize Your HMI With Smart Keypad Technology From ALMAX

The ALMAX Smart Keypad technology is an efficient way to add a keypad to an existing system. It can reduce GPIO usage, reduce processing consumption, and reduce the time-to-market for your upgraded product.  Our smart keypads are pre-built with a custom programmed microcontroller that relays button presses to the host system.
