PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.

It has 8 keys which can be connected to any microcontroller or any interfacing kit directly. KEY is a small key pad designed to data entries for microcontroller board.The board has 10-pin header for 10-wire ribbon cable. By default the switch status would be pulled up, every time you press a key the corresponding switch header changes its state to the common header in the board.

Note: The color of the PCB may vary. However the circuit/pinout of the PCB will remain same.
