Are you considering developing an i2c version of this product?
PCA9685 16-Channel 12-Bit 5-Amp High-Current N-Channel PWM Pulse Width Modulation Light Dimmer with IoT Interface
I will recommend using the SI adapter. it will convert it into an I2C board.
This is good news. I think it makes this card more suitable for a few needs i decribed in another thread, not having to break apart items accross so many channels to fit underneath an 8w power envelope…
