Shield Pca9685 16ch 12 Bits Pwm Servo Motor Driver Arduino Itytarg

Description:                     
Programmable LED brightness 
Programmable group fuzzy (DIM) / flicker with separate LED brightness blend 
1MHz fast mode Plus compatible with 30mA high drive capability on the I SDA2C bus interface to drive high capacity bus 

Each LED output can be achieved from completely off (the default) to the maximum brightness of the 4096 level (12 bit) linear programmable brightness 
Software programmable open drain output selection for LED (the default is 16 push-pull output push-pull) (under the 5V and 10mA absorption 25mA sink current pull current), no input function 

The output state can be programmed to change at the time of the response or stop command, to achieve the simultaneous update of all output or byte by byte (byte-by-byte) update output (default to "stop command changes"). 

Low effective output enable input pin, when the pin is high LED output can be programmed to 0, 1 or high resistance state (up to the power of the default high resistance) 
6 hardware address pins that make the same I262 PCA9685 devices can be connected to the C bus 

LED output frequency (all LED) is typically 40Hz to 1000Hz (when the oscillator is 25MHz, the default value of the pre divided frequency register 1EH will generate 200Hz refresh rate). 
4 software programmable I2C bus address (a LED group call (Call) address and three LED call (Call) address) makes the device in any combination group can be addressed at the same time (for example, a register for "all call (All Call)" I2The C bus on all PCA9634 devices can be addressed at the same time, while the second registers for three different address, then in a group of 1/3 bus equipment equipment can be addressed at the same time), can enable and disable I software2C bus address 

SWRST (Call I) enables the device to pass through the2C bus reset 
25MHz crystal, no external devices 
Maximum allowable 50MHz external input clock 
Internal power on reset 
Noise filter at the SDA/SCL input 
Output pin has edge generation rate control 
There is no burr (glitch) output on power up. 

Support thermal access 
Low standby current 
Operating voltage range: 2.3V to 5.5V 
Can withstand 5.5V input 
Can work in minus 40 degrees Celsius to 85 degrees Celsius in the environment 
ESD protection over HBM/JESD22-A114200V MM/JESD22-A115 2000V and CDM/JESD22-C101 1000V 
JEDEC standard 100mA into lock test when exceeds JESD78
