Loading 3D model… large boards can take a moment.
I love the idea of GreatScott`s Online Water Tracker, but unfortunately it was really difficult for me to implement his circuit on a perfboard, so I designed a cheap PCB for this.
Please notice, that this board does not replace/include the charge circuit (TP4056) or the boost converter. It only replaces the big ESP circuit.
The PCB has also some improvements:
Before you order the PCB, make sure you have all the needed components. You can find them here. Also don't forget to 3d print the case.
Ready? Let's go. I always order my PCBs via JLCPCB, a chinese PCB manufacturer.
After all you got 5 PCBs for less than 10€.
Just open an issue :)
