ZAF Plus Motor driver
For a detailed explanation of the connections, please refer to the original ZAF page.
The main difference between ZAF+ and ZAF is that for ZAF+ the PMW connections are coming from the Arduino Mega. In our ZAF+ design we have 4 motor drivers to connect the increased number of pumps (compared to ZAF). This can be easily scaled up if you need a device capable of controlling food distribution for more than 30 tanks.
