We’re all the time looking out for attention-grabbing little interface doohickeys! This small button cluster caught our eye because it seems to be actually neat and will add a contact of business design to your subsequent challenge. The Navigator Plus is just 5 buttons on a PCB. The buttons are neatly clustered to create a round array with a button within the centre. Every of the outer buttons has an arrow marker and the centre button has a dot. Every of those acts as a subtle window to five particular person white LEDs constructed into the module.
Every button has a broken-out pin and an inner pull-up resistor. The opposite facet of every button is wired on to a typical floor which is damaged out to a single pin. This makes it easy to attach up however means it might solely actually be utilized in designs that momentarily join an I/O pin to floor to sign button presses.
Equally, every of the LEDs is damaged out to a pin with the unfavorable terminals all linked to floor. Utilizing GPIO pins in your microcontroller that may drive an LED accurately makes utilizing the backlight a lot less complicated. All of the pins, each LED and buttons, are damaged out to plain 2.54mm spaced pin headers making the module breadboard suitable.
Wanting on the brief video beneath they’ve an instance the place the LEDs on the machine flash in a sample because the machine initialises. We hadn’t thought-about that as an thought, but it surely seems to be nice! At an estimated 20-25mm diameter we might think about these modules discovering their method into all method of initiatives.
