16×2 LCD using HD44780-compatible display module (white characters on blue background).
5 buttons on one analog input (A0).
LCD backlight with current limiting, brightness and on/off controllable by D3, can be moved to D2, D10, A1, A2, A3, A4 or A5 for easy project pin compatibility.
Recessed LCD, panel mount screw holes and button layout suitable for panel or cabinet mounting if desired.
Reset button.
Gold-plated PCB for maximum durability.
Overlay printed on both the top and the bottom.
