Modular Hydroponic Tower Garden V1.01

This is my second attempt to design a programmable water pump controller. It's capable to drive a variety of pumps using 12/24V power source up to a few amps of current. It has a "big" N-MOSFET capable of handling several amps of current and an ATmega328P microcontroller that is programmable via micro-USB connector or ISP-6 connector. It has also an I2C connector for LCD and two thermistor inputs for measuring temperatures (ideally the external temperature and the temperature inside the growing tower). The power input has reverse polarity protection using a P-MOSFET. The water pump has to have the same voltage rating as the input voltage. There's a V1.02 version already designed in which I moved the LEDs a bit aside.

    First time ordering av PCB and it turned out really good. It's an adater to adapt a PS2 mouse to old Amiga's, C64, C128 computer from the 80's. And it's also can adapt the old 8 bit NES controller to ...
    Clear resin print of a personalised belt buckle and I am shocked at how good it looks and how clear it actually is for 3d printing. It looks like it was made from a solid piece of acrylic. Shipping wa...
    Good stencil quality.
    This was my last production run of PCBs for assembldy at home with my own PnP gear. Going forward I'm going to work with PCBWay to optimize production volumes and timelines since they're so efficien...
    Quality of the PCB was great. Delivery time very acceptable.
    Good solderability, EMI, and overall quality. On-point dimensions for DIN connector.
    Good Quality, Fast Shipping. And, Faster than ordering in my country. :D
    My parts were machined quickly and shipped very fast. Excellent quality machining and all dimensions are in tolerance and price was lower than the competition. Expectations were exceeded. I will defin...
