If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with PWM outputs,  then the limited PWM outputs of your microcontroller would be a big problem for you. To overcome this problem, the only thing you should do is to get a 16-Channel 12-Bit PWM/Servo Driver.

You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.

It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good when you want to control white or blue LEDs with 3.4+ forward voltages. 6 address select pins so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs.Featured By RoboticsBD.

Product Images are shown for illustrative purposes only and may differ from the actual product.

The VCC pin is just power for the chip itself. If you want to connect servos or LEDs that use the V+ pins, you MUST connect the V+ pin as well. The V+ pin can be as high as 6V even if VCC is 3.3V (the chip is 5V safe). We suggest connecting power through the blue terminal block since it is polarity protected.

Answer: The board is designed to be 5V compliant, as stated in the description. Using a voltage higher than 6V may result in a short circuit. We have sold many of these modules and have received similar reports of issues caused by using higher voltages

Answer: At RoboticsBD, we prioritize quality over everything else. While many suppliers may choose cheaper sources in China, we’re committed to providing the best possible products within budget constraints. In an open market, balancing pricing and quality is crucial, and we never compromise on the latter. We believe our pricing is highly competitive, but we understand the importance of ensuring clarity. We encourage you to review the product again, as there may be confusion between different offerings in the market. In today’s online landscape, some websites may offer enticingly low prices without actually having the product in stock. These sites often aim to attract traffic and sell user tracking data for profit. However, they’re easy to spot: Unrealistically low prices compared to the market. Product consistently out of stock. Lack of a physical address. At RoboticsBD, we value transparency and integrity in all our dealings. Your trust and satisfaction are our top priorities.
