sku: 1170343
Shipping from: China
Features This board chip uses I2C 7 bit address between 0x60 0x80 selectable with jumpersTerminal block for power input or you can use the 0 1 breakouts on the side Reverse polarity protection on the terminal block inputGreen power good LED3 pin connectors in groups of 4 so you can plug in 16 servos at once Servo plugs are slightly wider than 0 1 so you can only stack 4 next to each other on 0 1 header Chain able designA spot to place a big capacitor on the V line If you need it 220 ohm series resistors on all the output lines to protect them and to make driving LEDs trivialSolder jumpers for the 6 address select pinsi2c controlled PWM driver with a built in clock Unlike the TLC5940 family you do not need to continuously send it signal tying up your microcontroller its 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 for 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 that s a lot of servos or LEDsAdjustable frequency PWM up to about 1 6 KHz12 bit resolution for each output for servos that means about 4us resolution at 60Hz update rateConfigurable push pull or open drain outputOutput enable pin to quickly disable all the outputs Package included 1 x PCA9685 16 Channel 12 bit PWM Servo Motor Driver I2C Module ForRobot
