Possibly a very basic question, but I am trying to add a secondary sub-board (receiver) to a micro controller for roller shutter door.

The control board already has a right angle 6-way pinout with 2.54mm pitch. This connects directly into the existing sub-board (receiver).

What I would like to do is to somehow passthrough the pinout to another receiver with the same pinout using simple wires.

The image below shows the current state with the purple existing board connected directly to the right angle pin-out from the control board. The new board is in blue, however they can be swapped around. The order doesn't matter.

My question is: how can I connect a secondary board (shown in blue) to the existing pins? I can't access the pins directly as there are plugged in. I'm guessing I would need some kind of pass-through device or splitter.

EDIT: Would the below configuration work on a stripboard?

  • \$\begingroup\$ I understand correctly, though: your board is blue in your drawing, and the existing sub-board is violet? Also, would it be possible for the blue and the violet board to swap places? \$\endgroup\$ Commented Mar 7, 2020 at 23:51
  • \$\begingroup\$ yes you understood correctly :) the two boards could in theory be swapped... but I'm not sure what this would achieve? Essentially the two boards would be powered by the same 12v pin, connect to the same GND pin and send power to the same control pin independently. \$\endgroup\$ Commented Mar 8, 2020 at 0:01
  • \$\begingroup\$ I think you should add that info (can be swapped) to the question, it's helpful for answers :) \$\endgroup\$ Commented Mar 8, 2020 at 0:07

The simpliest way would be soldering wires on each pin. Use only single strand (monolithic) wires. You can make use of prototype board, cut to desired size, to solder a female connector and a male connector in the appropriate direction to connect the original boards and then add the wires to the secondary sub-board. It will look more solid. But maybe not necessary.

Note that there is no garantee that the secondary sub-board will be recognized by the system or will work properly. But that already another topic.

  • \$\begingroup\$ Where did he say that? According to his drawing it should be possible. Thought a picture would help. \$\endgroup\$

  • \$\begingroup\$ Thanks. If I have 6x1 row pins, I could use a proto board with the same dimensions, solder on a male and female connector to act as a pass through and have the cables soldered in between? On your second topic, its a simple garage remote receiver. It only has V+, GND, and OSC pins. Having multiple receivers shouldn't be a problem. \$\endgroup\$ Commented Mar 8, 2020 at 0:50
  • \$\begingroup\$ Yes, you just need three rows of holes. (unless you want to add some extra components like led indicators) \$\endgroup\$

Yes your suggested man in the middle board would work, physically. As your diagram shows, you just need a 0.1" /2.54mm female header with extended leads (aka a stacking header) for the first board and some regular male headers for the top.

Without knowing what the boards actually are we cant say that the stacking would work though. Power would, but we cant say for sure for the oscillator pin or what the other 3 pins do at all.
