2X MCU-PCA9685 16-Channel Servo Driver 12-Bit Fm+I2C Bus PWM Controller Servo Control Module Popis

1. MHz Fast Mode compatible I2C bus interface with 30mA high drive capability SDA to drive high capacitive buses;Each LED output can achieve 4096 levels (12 bits) of linear programmable brightness from completely off (default) to brightness.
2. 16 push-pull outputs (sinking 25mA sink current and providing 10mA source current at 5V) that can be software-programmed as open-drain LED output selection (default is push-pull), with no input function.
3. The output state can be programmed to change response or stop command to update all outputs simultaneously or update the output byte-by-byte (default is "stop command change").Low-active output enable input pin, when this pin is high, the LED output can be programmed to 0, 1 or high impedance (default is high impedance at power-).
4. 6 hardware address pins allow 62 PCA9685 devices to be connected the same I2C bus LED output frequency (all LEDs) is usually 40Hz to 1000Hz (when the oscillator is 25MHz, the default value of the prescaler register is 1EH, which will produce a refresh rate of 200Hz).

4 software-programmable I2C bus addresses (one LED group call address and three LED sub-call addresses) allow device groups to be addressed at the same in any combination (for example, if a register is used for "All Calls", all PCA9634 devices the I2C bus can be addressed at the same , and the second register is used for three different addresses, then 1/3 of the devices the bus in a device group can be addressed at the same ), and the I2C bus address can be enabled and disabled by software.
