So, if I understood properly, using one pca9685 i get get 16 power outlet (8 for each DB9 on the pca9685) using only one DB9 on the controller (the one connected to the pca9685)
But what if my relay board only has 4 channels ? Can I connect two 4 channels relay boards to a single DB9 ?
Let's assume I need 16 power outlet but I can just use multiple 4 channels relay boards. Any idea ?
