Beschrijving

This is the base board version 1.1 of the current S32 Gateway.

So it’s the S32 internals without the microcontroller, enclosure, cables etc.
You will receive only the part exactly as it is shown in the image above.

If you use this board and a NodeMCU-32S (not included), you can easily build your own Gateway ready for EMS-ESP V3.
Just load the firmware and plug the ESP on the board, no Dupont wires needed. For some instructions see HERE.

This board is the complete circuit board that is inside the S32 Gateway.
It has a footprint for the NodeMCU-32S and it also has the JST connector for adding external Dallas sensors.
A premium quality buck type voltage regulator is on the board as well.

You can only use a real Ai Thinker NodeMCU-32S. (For instance an ESP32-DevKitC will not fit and it has a different pinout.)
You can use other ESP32 or microcontroller boards, but then you have to use DuPont cables to attach it.
See the pinout in the images.

This board can be powered from the EMS service jack or an external 6 to 12V DC power supply.
You can also power it via the USB connector on the NodeMCU-32S (not included).

All information on how to use this board see the dedicated wiki page HERE.

Dit product is GEEN directe vervanging voor de EMS Gateway!
Het is voor diegene die het leuk vindt om te hobbyen met electronica en programmeren.
Het is dus alleen de hardware interface tussen de EMS bus en een UART van een microcontroller. Dit product komt met geen enkele microcontroller of software.

    Would appreciate to include a cable for the PST connector (OneWire bus). I had to purchase these separately.

    The documentation is somewhat hard to read, since it combines all versions of the product over the years. It would be easier if separate versions/chapters for each board revision would be maintained.

    And most important: I would appreciate to get the schematics. There should be no secrets in the design. I bought it since it saves me time to do my own and it is much neater. So why not release the schematics?

    Thanks for all the good work, it’s really appreciated.

    Funktion einwandfrei. Man sollte aber darauf hinweisen, dass das ESP32 Modul einen Stiftabstand von 22,5mm haben muss. Es gibt bei diversen Händlern Module mit 25,0mm Abstand. Die passen nicht!

    The EMS Gateway S32 base board works perfectly. The online Wiki provided all necessary info regard functionality and connections. I’m finally able, with this board together with Homeassistant and Grafana, to fine-tune my recently bought Nefit Trendline II. The panel of the Trendline is providing some info regard settings and sensors, but I was looking for time based graphical charts, regard the performance of the Trendline in my house environment, during the daytime.
