PCA9685 PWM servo driver I2c interface

DIY KIT 16 Channel 12-bit PWM/Servo Driver-I2C interface-PCA9685 for UNO or Raspberry pi shield module servo shield

6 LED drivers, each output can be programmed to:
Turn off
Open
Programmable LED brightness
Programmable fuzzy group (dim) / Flashing LED brightness independent mixed with
1MHz Fast-mode Plus is compatible with high drive capability has 30mA on SDA I2C bus interface to drive highly capacitive bus
Each LED output can be achieved from the fully closed (the default) to 4096 (12) between the maximum brightness linear programmable brightness
Software programmable open-drain LED output selection (the default is a push-pull) of 16 push-pull outputs (at 5V 25mA sink can absorb and provide 10mA current draw), no input function
Programmable output state is in response to an order to change or stop to achieve simultaneously update all outputs or by-byte (byte-by-byte) update output (default is "Stop command to change")
Effective low output enable input pin when the pin is high, the LED output can be programmed to 0,1 or tri-state (high impedance power-on default)
6 hardware address pins so that the same can be connected to 62 PCA9685 I2C devices on the bus
LED output frequency (all LED) is typically 40Hz to 1000Hz (When the oscillator is 25MHz, the prescaler register default value 1EH 200Hz refresh rate will generate a)
4 software programmable I2C bus address (an LED group call (Call) address and three sub-LED call (Call) address) such that the device can be set in any combination to be addressed at the same time (e.g., a register used for " All calls (All Call) "then all PCA9634 devices on the I2C bus can be addressed at the same time, while the second register for three different addresses, then a device group 1/3 bus devices can be addressed at the same time), you can enable and disable the software I2C bus address
Software reset feature (SWRST Call) allows the device via I2C bus reset
25MHz internal oscillator requires no external components
The maximum allowable 50MHz external clock input
Internal power-on reset
In the SDA / SCL inputs with noise filter
Output pin has edge generation rate control
No glitches on power-up (glitch) output
Hot-Access
Low standby current
Operating voltage range: 2.3V to 5.5V
5.5V tolerant inputs
Can operate at minus 40 degrees Celsius to 85 degrees Celsius environment
