Button R click is the simplest solution for adding a single pushbutton to your design. The button itself is transparent, 6.8mm in diameter and has a red LED backlight. When pressed, it sends an interrupt signal to the target board microcontroller. The backlight LED is controlled separately through the mikroBUS™ PWM pin, so you can program all kinds of patterns (varying level of light intensity or rate of blinking on subsequent button presses). The board can use either a 3.3V or a 5V power supply.
