PCA9685 16 Channel PWM Servo Control Module 12 Bit Fm I2C

product description characteristic: - 1MHz Fast-mode Plus 30mA High Drive Capability on SDA Compatible with I2C Bus Interface to Drive High Capacitive Buses - Each LED output can be fully closed (default) to 4 (12) Linear Programmable Brightness - Software Programmable Open-Drain LED Output Options (Push-Pull by Default) 16 Push-Pull Outputs (5V Receptacle at 25mA with 10mA Source Current Available), No Input Function - The programmable output status is changed or stopped in response to a command to enable all outputs to be updated at the same time or updated byte-by-byte (by byte) (default "stop command change") - Active low output enable Input Pin When the pin is high, the LED output is programmable as either 0, 1, or 3-state (high impedance power-on default) - 6 hardware address pins to allow the same I2C device to be connected to the bus 62 PC 85 - The LED output frequency (full LED) is typically 40Hz to 1000Hz (the prescaler register defaults to 1EH when the oscillator is 25MHz and will result in a 200Hz refresh rate) - 4 software-programmable I2C bus addresses (LED Group Calls Call address and three LED sub-call (call) addresses) so that the devices can be set to be simultaneously addressed in any combination (for example, "All Calls (All Calls)") and then all PCs 34 devices on the I2C bus can address simultaneously, and the second register has three different addresses, the device group on the bus device can simultaneously address one-third) and the software can enable and disable the I2C bus address - the software Reset Function (SWRST Call) Reset Device via I2C Bus Reset - 25MHz Internal Oscillator No External Components Required - Maximum Allowed 50MHz External Clock Input - Internal Power-On Reset - SDA / SCL Input with No Noise Filter - Output Pin Has Edge generation rate control - No glitches on power output - Hot swap - Low standby current - Operating voltage range: 2.3V to
