I bought this thinking my black box needed the analog conversion, but it wasn't really working right (at about 15% dimming in reef-pi the light just went full-bright, no brightness change the rest of the way to 100%). I messaged Michael on R2R to ask about it and he suggested the light might be expecting the PWM signal directly (no analog conversion). Awesomely, he suggested an alternate wiring so the Mars Aqua adapter is still providing the ground, the v+, and the on/off signal, but the PWM is coming straight from the goby HAT and it's great!
With a little trimming, this fit the canakit's case for the pi4 (the lid doesn't fit, obviously). So far, this is great for my reef-pi. I gave 4 stars for documentation because there are some things that are different (usually simpler) than the adafruit guides and it's not always obvious what the distinctions are. Also, some of the documentation is accurate, but difficult for us non-hardware guys to know about (eg 1w vs 3v3 on the temp probes)
Very happy customer, just giving the best feedback I can.
Picked up the Reef Pi Hat v2 and the isolated pH boards for my Reef Pi controller. Both boards arrived quickly and were diligently packaged. To say that these boards are great would be an understatement.
Both boards are thoughtfully and efficiently laid out, which allows for a clean, professional-looking install and easy wire management.
Lastly, Mike's post-purchase support for this product is exceptional. Whenever I had a question and reached out on R2R, I typically heard back within hours. Superb!
Would absolutely recommend Mike's services/products to anyone looking to dip their toes into DIY aquarium controllers.
Excellent product working right now and could not find any problem.The board is perfect for the price.Could not find better PH interface for that price and mach perfect with my Reef-Pi.Would be nice to have more board like this for ORP and SG.Thank you.
Excellent product make my life easier,and my Reef-Pi build is easy and fast. Packaging was excellent and even include wire what i forget.Just need to thanks to Michael for that board and the Packaging.Would love to order more from this person and Tindie site
