Oh and also another question. Is the schematic in the folder correct to run under 5v?
I don't have much knowledge about circuits. The schematic works for me, which is the only thing I can tell you.
So I´ve been searching a bit more, and from the docs within the downloadable files, I can see this schematic
Later surfing the blog I found this one which seems to be more complete.
They are equivalent right? I mean the second is better because of the diodes and stuff..

The complete one is supposed to be used for both BrewManiacEx and BrewPiLess. The parts for BrewPiLess only are removed in BrewManiacEx github.
So thats the one i have to use. The complete one.

I don't understand your BC337 or BC547 implementation on the pcb board. I can't seem to find any that come in a triangle shape...Do I just bend the middle pin? Thanks
Double layer is too complex for me. Already made a single layer PCB. Will post it today maybe.
So. This is what i managed to do within a 100x100mm pcb board.
Tracks are 1.5mm wide so they might be good enough for tonerr transfer.
I´ll be using a PCF8574 module like the one you see in the attached images for the buttons.
The I2c LCD module, and the buzzer.
There is one wire that has to go in the upper side of the pcb between male headers, and thats for feeding the mosfets with 3.3v.
The rest is single layer.
My intention is to use a PC power supply, so i can get both 5v and 3.3V.
Please any feedback will be appreciated.
I´ll post a public schematci so that anyone can improve this.
EDIT: Project page added.

You can save the .zip files from this link and send them off to DirtyPCB and have the boards made.

That is correct, you just bend the legs. quite standard mounting for TO-92's because it is easier to solder than when they are straight in a row
Bigdaddyale: have you ordered and finished the boards?

No, I haven't ordered the boards yet.Thank you for releasing the files.

I should find someone here in Argentina to make it, because getting something from another country is an odissey. And time consuming.
Bless my customs.

https://pcbs.io is the cheapest way (4 boards for $4) to do this, with free and fast shipping, and you turn your project available for everybody around the globe.
You mean like an ATX supply? Massive overkill, don't you think?
Yeah I began thinking about it. Might use a 3.3v regulator and a phone charger for powering everything else.
There are very few components. Unless your SSR drains a lot, more than 1.5A should be enough.(Correct me if I am wrong.)
I have been using a small 2A/5V power converter, and I don't have any trouble.
Well then that's great. I'll try making the PCB today. I'm a bit short of time.
Figured it out. Installed platformio and uploaded the files that way.
I've been losing my mind for the past day because the WifiManager would never show up as a AP to connect to. I finally realized that the WEMOS was already connected to my network; apparently the WEMOS (And other ESP8266?) stores wifi network credentials somewhere that doesn't get wiped out by standard flashing.
Everything is awesome, except.... I cannot get the WEMOS / shield to recognize the DS18B20 sensors. Any idea what I'm doing wrong? Black wire -> GND, Yellow wire -> DATA, Red wire -> 3V#

Are you using multiple sensors? You might try single sensor first.
Or, you can google "DS18B20 Arduino" to find a bunch of sample code.
If you connect multiple sensors, you must use the multi-sensor binary. Setup is necessary for multi-sensor.
using the following
[env:nodemcuv2-multisensor]
platform = espressif8266
board = nodemcuv2
framework = arduino
build_flags = -Wl,-Tesp8266.flash.4m.ld -DEnableMultiSensor
and
platformio run -e uno -t upload
Result:
# Address
1 0xFFFFFFFFFFFFFFFF
I did not, I don't think. Does that require input and LCD? http://vito.tw/?p=435
Yes. That is the (maybe) only one thing that is missed from the web interface.
https://github.com/vitotai/BrewManiacEsp8266/blob/master/docs/BrewManiacExManual_0.3.pdf
You can use the buttons on the web to control it, but you can't see what on the LCD in setup procedure.
It is because I use this keypad:
https://www.ebay.com/itm/2PCS-1x4-M...ad-Keyboard-1-4-Keys-for-Arduino/321485262764
If you are using regular buttons, the arrangement should not be a problem. You can change the setting in the code easily, too.
I am no expert about circuits.
AFAIK, you feed 5V to D1 mini only. There is a regulator, RT9013, that converts 5V to 3.3V.
Yeah I know, but I meant, if I feed the circuit with 5v, will the 3.3v leg output me 3.3v with enough power for the transistors?
The spec. says 500mA while ESP8266 requires 300mA max. I don’t know how much GPIOs draw and transistors need.
You might need to find out the numbers and do some math.
I would bet it is enough if you don’t run other components on 3v3 domain.
Do I set it via code or trough the a0,a1 and a2 dip switch on the pcf5674 module?
