Mounting IR-Receiver module on a PCB

Other Hardware General Electronics
1

please advice, how to mount the IR-receiver Module on a PCB: on actual production PCB, not on a Breadboard. The Nano itself will be plugged into a strip of header socket on board, the other components will be soldered to the PCB. How to properly arrange and fix this module on a PCB?

  • You can buy the receiver and solder it on your PCB like any 3 terminal device.

  • The TSOP4836 should work for this.

  • If you need to use that module, solder a 3 terminal female Dupont header on the PCB.
    Alternatively, you can just solder the module directly to the PCB.

Why not do the same with the receiver?

Don't forget that the module needs direct visibility of the transmitter to receive, so place it near the window in the case with the side opposite the pins

Is there a reason to use a module on pcb instead of plain receiver?

5

These Vishay TSOP4836 or Infineon SFH5110 are single chip solution, that replace that module? Does it require a the pull-up resistor on PCB?

  • The data sheet shows an internal pull-up in the device already.

In other words, that module exists only to be easy to connect with jumper wires....

  • Well the board has a LED on it. :wink:
9

Right, and a resistor for it! :grinning:
Some "modules" have nothing else than sensor....

10
  • Well, the LED at least monitors the receiver output so that might be a good troubleshooting aid. :thinking:

Right, I agree... Some benefits you get.
Common transmitter module without transistor circuit:

  • Something is wrong, maybe the TX LED is not the correct wave length or you have a faulty LED ?
    Similar hardware here works at 30 feet.

  • If the TX LED has a series resistor, what is its value ? :thinking:

Sorry, I was meant to be ironic about modules that do nothing beyond the single component on it.
That emitter module has resistor to drive the led at few mA.
Common remote control drives the IR led at >100mA, sometimes with current limited only from battery discharge capacity.
But transistor would add a penny to the cost...

Why are the module pins bent at 90 degrees?

15

Why not?
Why is the LED bent 90deg?

16

Why is the sky blue? Many modules include 90 degree and straight pins to facilitate mounting of the module. The end used decides how they choose to mount the module.
