This chip can control 24 separate channels of 12-bit PWM output for LED control, this board is not good for driving servos. For servos use this servo driver.
Features:
- SPI controlled PWM/LED driver board
- 24 Channel
- Constant-current & open drain outputs
- Input Voltage: 5V - 30V
- Uses SPI to communicate
- 3 pins are required to interface:
- Data
- Clock
- Latch
- Boards are chainable
- Output Enable (OE) allows you to turn off all outputs at once
- Max Daisy-chaining: no maximum, just supply enough power and you can chain as many as necessary
- Constant current so LEDs won't flicker or burn out
- Current level: 15mA per channel (can be adjusted by soldering a different resistor
- Resolution: 12 bit
- Arduinio Hookup:
- LAT: Arduino D6
- OE: no connection
- CLK: Arduino D5
- DIN: Arduino D4
- GND: Arduino GND
- V+: Arduino VIN or external power supply
