It supports 5V logic while being compatible with 3.3V MCUs like Raspberry Pi and Arduino. With built-in clock and free-running PWM outputs, it enables smooth, precise control of up to 16 servos or LEDs simultaneously, and can be chained to control nearly 1,000 outputs. Ideal for professional makers seeking scalable, high-resolution PWM control without sacrificing MCU resources. ## Description Introduction PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. 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.

Review: Einwandfrei - Habe dieses Modul für die Steuerung von LED Leisten an einem Raspberry gekauft. Allerdings beträgt die PWM Frequenz maximal 1 kHz. Dadurch erzeugt das Netzteil Störgeräusche in diesem Bereich. Bei niedrigeren Frequenzen wird das Geräusch leiser, allerdings beginnen die Streifen dann zu flackern. Erfahrungsgemäß funktionieren LED Streifen am besten mit >20 kHz. Dann sind die Störgeräusche im Netzteil auch nicht mehr hörbar und das Netzteil wird entlastet. Hierzu am besten einen Arduino verwenden und alle PWM Frequenzen auf 32 kHz einstellen. Das Modul selbst funktioniert wunderbar und ist für Servo-Ansteuerung bestens geeignet. Review: Producto adecuado. - Funciona muy bien, aunque el bornero para cables es muy reducido, y sólo apto para cables de 1,5mm2. ## Features - Contain an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running - 5V compliant, which means you can control it from a 3.3V microcontroller (this is good when you want to control white or blue LEDs with 3.4+ forward voltages) - Support using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs - 3 pin connectors in groups of 4, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header - 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014KTSMLA | | Best Sellers Rank | #92,511 in Computers ( See Top 100 in Computers ) #1,434 in Single-Board Computers | | Brand | SunFounder | | Built-In Media | 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver | | CPU Model | 210 | | CPU model | 210 | | CPU speed | 1 KHz | | Compatible Devices | Servos | | Connectivity Technology | I2C | | Connectivity technology | I2C | | Customer Reviews | 4.4 out of 5 stars 403 Reviews | | Included components | 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver | | Item Weight | 0.02 Pounds | | Manufacturer | SunFounder | | Mfr Part Number | miniLCD | | Model Name | PCA9685 16 Channel 12 bit PWM Servo Driver | | Model Number | miniLCD | | Model name | PCA9685 16 Channel 12 bit PWM Servo Driver | | Operating System | Raspberry Pi OS | | Processor Brand | Intel | | Processor Count | 16 | | Processor Speed | 1 KHz | | RAM Memory Technology | LPDDR4 | | UPC | 701715367203 | ## Product Details - **Brand:** SunFounder - **Model name:** PCA9685 16 Channel 12 bit PWM Servo Driver - **CPU model:** 210 - **Connectivity technology:** I2C - **Included components:** 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver ## Images ![SunFounder PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino and Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/61W+eG+LigL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Einwandfrei *by O***A on 4 February 2020* Habe dieses Modul für die Steuerung von LED Leisten an einem Raspberry gekauft.
