yesh I know that I al aware hence going for the more expensive pumps. They are not as expensive as atlas ones but that’s only because they don’t have integrated motor driver with each one. If I had there pumps I wouldn’t need the motor drivers boards.
Build one with 12v peristaltic pumps and H Bridge motor driver. I used to use L298n but recently swapped to a board Adafruit makes which is a PCA9285 with two TB6612 which gives you 4 outputs per board. I also automate my dosing of nutes etc so I first lower the speed of the pump and then coding...
Did anyone give this PCB a go or use the same schematic but on a breadboard or similar? I got the impression that @shimbob sensed a problem with more than 2 fans on this? Or is it more than 1?
I might use this with some of LEDGardeners PCD designs to do something similar. That reminds me, I...
