Part 3: Adapter-LK for Grove connectors

By | 12. March 2019

Basics of the Grove connector system.

Why Grove plugs?


A table top assembly (almost) only with finished Grove modules.

  • Solderless connector system
  • This greatly reduces the chance of miswiring.
  • No forgotten pull-up / pull-down resistors…
  • A repair / component exchange extension / troubleshooting at the apiary is also much easier due to the “reverse polarity protected” plugging.
  • If the cables are labeled on the Raspi side, miswiring is almost impossible. (If one still manages to read the small font on the board due to age
  • Questions like: “In which pin does the green cable belong now?” and “Why are there two green cables?
  • Almost without instructions mountable.
  • If you buy the Grove plug adapters LK now somewhere ready, it would go completely without soldering…

The files for the PCB can be found here:

The file contains the Gerber data: The layout was created with Eagle and the Gerber data was exported from it. This data must be uploaded to the PCB manufacturer:


I ordered my circuit boards here (in China):


Simply drag the zip file (marked yellow above) with the Gerber data into the field “Add your gerber file”.

With me all order options were then correctly adjusted, and I only had to pay.


10 pieces for approx. 2€ + 5€ shipping costs

After about 2 weeks the boards were in the mailbox.

Nach ca. 2 Wochen lagen die Boards im Briefkasten.

I have only equipped the 8pcs Grove plug and the 40pin female connector strip to the Raspberry. On the board there are additional support capacitors and pull-uP resistors for the I2C interface to the BME680 sensor, but it works without them.

The soldering of the plugs is not very difficult, even children can do that… you only have to pay attention which plug is soldered from which side, I first soldered the 40pin plug and then the 8pc 4pc plug.

Here again the Reichelt order numbers for the plugs:×20-gerade-mpe-094-2-040-p199544.html?

    Hallo Alexander Bitte um Info , wo wird was eingesteckt, ich habe mir die Grove Base Hat von der Firma Seele
    Bestellt nun geht es darum welcher Fühler ,Taster, Led angeschlossen wird.

    Vielen Dank für deine Bemühungen Gruß Helmut

    wie hast Du den 4,7k Ohm Widerstand für den 1-Wire-Anschluss realisiert?

      Hallo Pascal,
      Schau mal unter Anleitungen, Brutraumtemperatursensor. Dort ist es gut erklärt. Mit Bild.
      Gruss Dieter

        Hi Dieter,

        es geht mir darum, dass ich auf der Zusatz-Platine eine 4,7k Ohm Widerstand erwartet hätte, für den 1-Wire Anschluss, nur keinen entdecken kann.

            besten Dank für die Info. Hättest Du Lust in einer der nächsten Versionen der Platine die Möglichkeit vorzusehen, einen Widerstand auf die Platine zu löten? Ich denke, dass würde sie was die Temp-Sensoren betrifft, flexibler machen.

    Das hat der Alexander wirklich toll gemacht. Genau wie das HoneyPi-Team hat er sehr viel Zeit (ehrenhalber) in das Projekt investiert. Ich nutze das System wie beschrieben, ein schliesslich der Platine, die man für ein kaum glaubhaft niedrigen Preis aus China bekommt. Das System läuft jetzt im Freien wie es soll. Ich bin gerade an der 2. und 3. Bienenstockwaage.
