Haha, disappointment is a part of life.

Don't be disappointed, my friend. Your contribution is very important to the hobby.
Here in Brazil, we are having a lot of difficulties with importing.
If you make something modular that a layperson only needs to connect the wires and put it up for sale, it would be much easier to reach a much larger audience.
I know the basics of electronics, but when it comes to programming, I'm the copy-and-paste type...
But congratulations on your initiative, and don't get discouraged, you're certainly helping a lot of people.

I cant for the life of me get the LED controller to work with LED current limiters, But I did use your project for something else.
I use an awesome and very cheap LED light from aliexpress, it has 2 channels ( blue and UV and white and UV) the controller is terrible SO I used your controller with some mosfets to make my own schedule. Right now im testing it om my 1 gallon food container Pico that is still cycling that only houses a BTA:



I'm ordering some more esp32s to do the same for my limonade jar pico

Great project.

Thank you. I'm working on it right now. This is a true all-in-one board. It only needs LEDs, a fan, and an NTC connected externally.

I tested my carrier/driver board. Here is the data at 100W, under natural convection (fanless), with a room temperature of 24°C, six channels each at 23.5V and 0.7A. The maximum surface temperature of the PCB stabilizes at around 80°C. With slight forced air cooling, it can be reduced to 54°C

Testei minha placa de circuito impresso/driver. Aqui estão os dados a 100 W, sob convecção natural (sem ventoinha), com temperatura ambiente de 24 °C, seis canais, cada um a 23,5 V e 0,7 A. A temperatura máxima da superfície da placa de circuito impresso estabiliza em torno de 80 °C. Com um leve resfriamento por ar forçado, ela pode ser reduzida para 54 °C.

I would love to test this in a terrarium set up. I have kept everything under the sun. Freshwater for around 50 years Arachnids for around 40 years. Saltwater for around 20 years. And over the last 10 years I have gotten into terrariums and some rarer plants.

I was happy to see this when I did as I was looking for an app with better/easier usage with a TC421. Plus I've been just searching for a different unit that could achieve what this has but better or more updated.

Thank you for your work and dedication.

Would this PCB work with your controller?

Thank you for your support and for sharing your 50-year journey in the hobby. It's an honor to hear from a true veteran.

Of course, it can be supported.

However, since the Meanwell LDD-700H is a product from ancient times, it only supports 1kHz PWM dimming. So, you'll need to first power on my controller, connect it to Wi-Fi, and then use the App to adjust the controller's PWM frequency from 19.5kHz down to 1kHz.

Here is the rest of the board.

Ahh an ole O2Surplus board.
Guess you'd just plug in where the Bluefish mini would have gone.
