Label:Yes
Reliable Works: Supports hot access as well as low standby current to make the performance more stable and efficient.It works stably in -40°C to 85°C environment, and has a low active output enable input pin for flexible output state setting.
Easier Control: No need to send continuously signals to tie down your micro controller, it is completely autonomous running. It has a 1MHz fast mode Plus compatible I2C bus interface, and the output state can be programmed to update all outputs simultaneously or byte by byte.
Easy to Install: 62 x 25 x 2mm compact size together with light weight will simplify the installation, time saving. Its small size fits well in limited-space scenarios.
Stable Driving: 5V compliant, so you can control it from a 3.3V micro controller and safely drive up to 6V outputs.It has 16 push-pull outputs, capable of sinking 25mA and sourcing 10mA at 5V for stable driving.
Adjustable PWM: The adjustable PWM frequency can get up to about 1.6KHz, which brings more convenience to adjustment. Each LED output has 4096-level (12-bit) programmable brightness, with usual output frequency of 40Hz to 1000Hz.
Specification
Item Type: Servo Motor Driver
Material: Resin
Size: Approx. 62 x 25 x 2mm / 2.44 x 0.98 x 0.08in
Model: PCA9685
Operating Voltage Range: 2.3V to 5.5V
Operating Temperature: Can work in the environment of minus 40 degrees Celsius to 85 degrees Celsius.
How to Use:
1.1MHz fast mode Plus compatible I2C bus interface with 30mA high drive capability on SDA to drive high capacitive buses.
2. Each LED output can achieve 4096 level (12 bit) linearly programmable brightness from fully off (default) to maximum brightness.
3. 16 push pull outputs that can be software programmed as open drain LED output selection (default is push pull) (can sink 25mA sink current and provide 10mA source current at 5V), no input function.
4. Output state can be programmed to change on answer or stop signal to update all outputs simultaneously or byte by byte (default stop signal change).
5. Low active output enable input pin, when the pin is high, the LED output can be programmed to 0, 1 or high impedance state (power on default is high impedance state).
6. 6 hardware address pins allow up to 62 PCA9685 devices on the same I2C bus.
7. The LED output frequency (all LEDs) is usually 40Hz to 1000Hz (when the oscillator is 25MHz, the prescaler register default value of 1EH will produce a renewal frequency of 200Hz).
8.4 software programmable I2C bus addresses (one LED group call (Call) address and three LED sub call (Call) addresses), so that groups of devices can be addressed at the same time in any combination (for example, a register for All Call then all PCA9634 devices on the I2C bus can be addressed at the same time, and the second register is used for three different addresses, then 1/3 of the devices on the bus in a device group can be address at the same time), software enables and disables I2C bus address.
9. The software reset feature (SWRST Call) enables the device to be reset through the I2C bus.
