Pinout.xyz VS Mycodo

Obligatory shameless plug of https://pinout.xyz where I’ve been maintaining an interactive Raspberry Pi SBC pinout for some years, and the newer https://pico.pinout.xyz where I’ve tried to do the same for the Raspberry Pi Pico board. The latter also became a command-line pinout via the Python package “picopins”

I feel- and of course I’m biased- that if anything is worth bringing to the table for device pinouts it’s interactivity and accessibility. The latter, in particular, is lost in static images. I really leaned into this with the Pico Pinout, including everything from visual accessibility accommodations (avoiding low contrast text background colours), to markup for screen readers to the ability to turn off labels and reduce noise. I’m still unsure if I actually achieved my goal, but it’s been fun.

There is a great resource to be found at pinout.xyz that details a lot of boards and the pins they actually use.

All the LEDs have their negative pins together and go through two 1k resistors in series on their way to ground (any gpio ground pin). Then a short piece of jumper wire goes from the positive lead of each LED to it's GPIO pin number. Don't use the pin order number, use the GPIO number.

I wanted to create an accessible alternative to the official Pico pinout image, offering more complete pin details, light/dark modes, screen-readable text, and at least some capacity to focus on the peripherals you’re interested in. It’s a sister site to the now ancient Raspberry Pi pinout (https://pinout.xyz/) which started out life hosted on a Raspberry Pi.

GPIO PIN numbers - its a real pain with both board and BCM numbers (see pinout.xyz for details) without having to translate what the libraries use by default!

The pins are at top right corner here: https://pinout.xyz/ and you just connect TX to RX, RX to TX and GND to GND. On the software side you can use picocom on the builtin serial device. Not sure which though, seems to depend on the software and exact revision of your RPi.

You can see all the pins on the pin documented at https://pinout.xyz

Use pinout.xyz to see what pins are used for the SPI interface on your Pi.

You have mixed up the PIN numbers - the Pi has two sets on numbers (board and BCM) - see here for details

For controlling everything, the plan is to use a Raspberry Pi running Mycodo, which will connect to the the temperature/humidity sensors, and also control the LED lights, the misting sprayers, and the heating coil.

As others have pointed out, there are quite a few alternatives already on the market, including open source ones. If you are attempting to turn this into a marketable product, you might be disappointed.

I'd also take a look at mycodo (here is the repo) which I personally found much more powerful than BrewPi and has an okay API I think if you want to set up your own frontend

Update: Found out about: MyCodo - https://github.com/kizniche/Mycodo (opensource Environmental Regulation System for rasbery pi) https://www.youtube.com/watch?v=nyqykZK2Ev4

Mycodo is great for the software side, but I don't think they have libraries for any wireless sensors.

There's tons of land unused in the US. But I also agree with you. I haven't played with this one yet, but it looks very nice

Inkbird has a good reputation at a relatively low cost. Personally, I like to build my own systems using the Mycodo system running on Raspberry Pi W's.

Here's my quick intro to hydroponics.

If you want bridge your grow with automation and coding I recommend everyone take a look at

If you're looking for instrumentation/controllers for your grow (CO2, PH, TDS, EC) I recommend:

If you're indoor and need lighting, build your own LED based lighting. Use the Samsung LM301B or LM301H led. I shopped https://atreumlighting.com/ for my last DIY kit and my light fixture came out perfect.

If you're buying nutrients or supplements, always try to get them in powered formula. Liquid based formulas are typically more expensive because you're paying to ship the water around and water is heavy. Most nutrient lines provide a feed schedule and dosing. When doing nutrients, less is more, never give them too much fertilizer, you will damage your grow and burn your plants.
