Servo motor driver board/ PWM 16 channel 12 bits PCA9685 I2C

Servo motor driver board/ PWM 16 channel 12 bits PCA9685 I2C

Product information:

This 16-channel PWM servo driver based on the PCA9685 chip makes it easy to precisely control multiple servos or LEDs via I2C. Thanks to 12-bit resolution and an external power supply up to 6V, it is ideal for robotics, lighting and embedded projects. Works with Arduino, Raspberry Pi and other microcontrollers.

Comes with loose header pins and screw terminals.

- 1MHz Fast-mode Plus compatible, 30mA high drive capacity on SDA or I2C bus interface to drive highly capacitive buses
- Each LED output can be achieved from fully closed (default) to 4096 (12) between maximum brightness linear programmable brightness
- Software programmable open-drain LED output selection (default is push-pull) or 16 push-pull outputs (5V at 25mA sink can absorb and supply 10mA source current), no input function
- The programmable output status is in response to a command to change or stop to update all output at once or byte-by-byte (default "Stop Command Changes")
- Active low output activates input pin when pin is high. LED outputs can be programmed to 0.1 or tri-state (default high impedance at power on).
- 6 hardware address pins so that the same I2C devices can be connected to the bus 62 PCA9685
- The LED output frequency (all LEDs) is typically between 40Hz and 1000Hz (when the oscillator is 25MHz, the default value of the prescaler register 1EH generates a refresh rate of 200Hz)
- 4 software programmable I2C bus addresses (one LED group call address and three LED sub call address), so the device can be set to be addressed simultaneously in any combination (for example one register for "all calls", then all PCA9634 devices on the I2C bus can be addressed simultaneously, while the second register is for three different addresses, then the device group on a bus device can be addressed 1/3 simultaneously), software can switch the I2C bus address on and off
- Software reset function (SWRST Call) ensures that the device is reset via the I2C bus
- 25MHz internal oscillator requires no external components
- The maximum allowed external clock speed of 50 MHz
- An internal power-on reset
- In the SDA/SCL inputs with noise filter
- The output pin has an edge generation speed control
- No output power disturbances
- Hot access
- Low standby current
- Operating voltage range: 2.3 V to 5.5 V
- 5.5V tolerant inputs
- It can work in the environment from -40 degrees Celsius to 85 degrees Celsius
- ESD protection exceeds 2000V HBM/JESD22-A114, 200V MM/JESD22-A115 and 1000V CDM/JESD22-C101
- JEDEC standard JESD78 in the interlock test above 100 mA
