PCA9685 16-Channel 12 bit PWM Servo Driver I2C Interface Fit for Arduino Raspberry
$ 26.64
116 LED drivers with programmable LED brightness, each output programmable: On/Off. 2Programmable group blur (dim) / flashing mixed with independent LED brightness. 3The output state can be programmed to change when responding or stopping a command to achieve simultaneous update of all outputs or byte-by-byte update output (default is "stop command change"). 4Each LED output achieves 4096-level (12-bit) linear programmable brightness from fully off (default) to maximum brightness. 525MHz internal crystal oscillator without external devices
