Connecting hardware without soldering

Hi,

I'm new to the Arduino - don't even own one yet.

I'm into Home Automation and currently using an RFXCom 433 transceiver with Domoticz on a Raspberry pi.

There are a few new devices I've got though and am thinking of trying RFLink which runs on an Arduino Mega with an RF 433 transceiver kit. The problem is that I'm not good at soldering and don't have a soldering iron etc, so I'm wondering if there's a way of connecting the transceiver to the Arduino without soldering?

I see that the various transceivers or transmitters and receivers have pins on them. Can I simply push the pins into the holes on the Mega, or do they have to be soldered?

Hope this makes sense, but if you need any more details or if I've posted this in the wrong place then just let me know.

Thanks

A shield, which is designed to be pinout compatible with an Arduino, can be plugged in.

The odds of the pinouts on a random non shield module you might want to use matching the pinouts on the Mega are essentially zero.

Do yourself a favour and learn to solder. There are countless "how to" tutorials available on the web. It will pay off big time in the long run.

It is not difficult to learn to solder, and when properly soldered, your projects will be vastly more reliable. Adafruit, Sparkfun and others offer excellent tutorials.

If you use RF devices that have pins already soldered, such as these, and use a wireless breadboard, and connect all with Dupont jumper wires, you can avoid soldering.

As a first step to connect everything you could use Dupont wires. Male to Female since you got a Mega. They are cheap and you can reuse them.

If you later on decides to use a PCB, then you need to have it soldered. There are protoboards, or you can make a layout and have a PCB house manufacture it (and even solder components if you want).

Good luck :upside_down_face:

With "small connections" soldering is sometimes the only option... If electronics is going to be your hobby you should have a soldering iron, a multimeter, and a few other little special tools like wire cutters.

I don't know the details of your hardware but here are some Ideas:

I've built a few permanent projects with breadboards. (There was still some soldering.) (1) I've got a couple of gizmos that have been working for decades!

I've built a couple of power supplies, making the connections with this type of screw-terminal block.. They come in different sizes (with more terminals) and you can cut them to whatever you need with a hacksaw.

Electricians use wire nuts to connect two or more wires. They can be used with resistors & capacitors and other components that have leads. Usually you need to use shrink tubing (or other tubing) to insulate the exposed part of the leads.

Crimp terminals can also be used to connect wires and components with leads (you need a crimp tool). Or crimp-on quick-disconnects can be used if you want the ability to un-plug the connection.

(1) I wasn't trying to avoid soldering... I was avoiding making a custom PC board, which was ridiculously expensive a few decades ago.

Since then I've designed a couple of custom boards (and had them fabricated by Seeed Studios). But they use through-hole connections. I DO try to avoid surface-mount soldering!

Wow!

Some really useful replies and very quickly! Thanks very much!

I've just picked the most recent post to reply to as it's easier to do a general reply than respond to each post specifically - hope this is ok?

Whilst I'd love to make a hobby out of electronics, I simply don't have the time at the moment for more than a bit of tinkering, so for now this is a one off project.

That's not to say it might grow into more, time and funds permitting :slight_smile:

From all the advice here I think Dupont wires are the way to go - either directly connecting them to the Mega or more likely using a breadboard - I'll need to get an enclosure at some point but that can wait till I've got it up and running.

I'm thinking of something like HUAREW Breadboard and Jumper Wires Kit Include 830 Tie Points Breadboard 400 Tie Points Breadboard Jumper Wire : Amazon.co.uk: Business, Industry & Science - does that look ok?

Thanks

That kit looks like it is all you need. Happy prototyping. :smiley:

Who knows, maybe Jessica would like tinkering with electronics and you can chime in once in a while. If your nickname reflects the real world that is. :upside_down_face:

I would get this instead:

Busboard Prototype Systems 830

ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female

Yes it's costs more, but frustration have a price too. I've been there, and this breadboard from Busboard is a breeze to work with. The Elegoo was a suggestion from Amazon, and I like it since Elegoo are well known, and here you get 40 + 40 long female to male jumper wires.

She might at some point - at the moment she's more into coding than physical electronics but you never know.

Thanks for the suggestion on the Breadboard but armed with the knowledge about Breadboards and Dupont cables I was looking for the transceiver module and came across DAOKAI 2Pcs NRF24L01+PA+LNA Wireless Module 2.4 GHz 1100m Wireless Transceiver RF Transceiver Module with SMA Antenna 3.3V Wireless Module Adapter Board for Arduino : Amazon.co.uk: Business, Industry & Science

Going with that I don't think I need a breadboard at all but will keep your suggestion in mind for the future as no doubt I'll probably want to start tinkering more :slight_smile:

EDIT - Back to the drawing board as the NRF24L01 is only for a specific set of sensors so will probably go with the breadboard once I find the right module.

Thanks

Spending the time to learn to solder will pay big dividends to you in the long run. Do not be foolish, if you are serious get a good iron, one that is temperature controlled and at least 50 watts. Also get a small assortment of tips and an extra heating unit for it. Use name brand solder in the 60/40 range that has a rosin core for starting.

Solder is a eutectic bond and it has to get hot enough to flow like water to fill the joint. If it is not smooth and shiny it is probably a bad joint. This will take several sessions to learn. Get some scrap boards and practice.
