555 Timer PWM Square wave signal generator 5-15VDC 100 mA
US$7.69
A small compact device that you use to create square waves. Change the frequency of the square wave with potentiometer next to the capacitors and change the duty cycle with the potentiometer next to the red led. You can also change the value of the capacitor with the Yellow jumper pin array, the marking L indicates the highest capacitance of 100uF, the second is 1uF, the third is 0.1uF and the last one with the marking H is 0.001uF or 1nF. Supply voltage to VCC and GND to GND from 5v to 15VDC, the Output pin can go to your device allow with common ground pin GND.

MOT-BTS7960B 43A H-Bridge BTS7960B PWM via microcontroller logic
US$27.93
Control a single motor in either forward or reverse direction by using this single module. The other end consists of a 2 x 4 header for connect a simple 5v logic from any microcontroller and some pwm signal to control the direction and speed. The other end can take an input voltage from 5 – 27v supply, flip the board to see the B marking. The output is W marking where you can connect any motor that can run from the input voltage range of 5 to 27v. You can put a maximum of 43A to this driver.

2946-ADA Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731
US$10.42
The IS31FL3731 will let you get back to that classic LED matrix look, with a nice upgrade! This I2C LED driver chip has the ability to PWM each individual LED in a 16x9 grid so you can have beautiful LED lighting effects, without a lot of pin twiddling. Simply tell the chip which LED on the grid you want lit, and what brightness and it's all taken care of for you.
