I am plug & play, non-soldering type.

As such, I love Grove Connectors.

Does anyone know of a non-soldering, preferably non-breadboard, way to use them with the ESP-WROVER-KIT-VB development board?

[Update] I never did figure out how to do this, and the only answerer hasn't logged in for a long time. Does anyone know how? I like the ESP-WROVER-KIT-VB because it had an on board debugger (and display).


I have some doubt I fully understand the question (as the answer seems too simple) but I'll try nonetheless.

Two options that came to mind right away:

  • Get a plain Grove I2C Hub with 4 ports or more, split a Grove cable on one end and attach individual jumper wires (similar to what I do here), plug those into the dev board.
  • Get a Grove Base Shield for e.g. NodeMCU, use male-to-female jumper wires to connect the MCU connectors on the shield with the dev board.


Here's a quickly stitched together photo more clearly describing (I hope) the 2nd idea. You can use any Grove Base Shield; nothing to do with NodeMCU. You will be feeding Vin/GND and the 2 I2C lines into the connectors of shield from the dev board. The Grove connectors will never know whether they are feeding or being fed by NodeMCU or the dev board.

  • You understood correctly (upvote), although I not sure if you fully grokked "I am plug & play, non-soldering type" :-) For instance "similar to what I do here" contains the words "Solder a jumper wire onto each strand of the Grove cable" and NodeMCU seems to be eSP286 based firmware. There are a few ESP32s which have Arduino pin-out, so I can use one pf those and a an Arduino Grove shield, but I would really prefer some kind of plug & play solution for the ESP-WROVER-KIT-VB development board – Mawg says reinstate Monica Dec 22 '19 at 8:34

    That's why I said similar - I'm sure there are creative ways to achieve the same without soldering. "NodeMCU" is both a dev kit and a firmware that allows you to program the ESP8266/32 using the Lua language (I'm a committer with that project). That's not the point, though. You won't be using NodeMCU at all. Allow me to update the answer and make that more clear. – Marcel Stör Dec 22 '19 at 12:00
  • Thanks! Look like I don't need to solder right? What about the wiring? Which pin goes to which? – Mawg says reinstate Monica Dec 26 '19 at 10:38
