Parallax Proto board USB to Breadboard w/o Soldering?

speewave

i have the ProtoBoard USB, and i want to do some prototyping.
i have a solderless breadboard and i just want to basically run some wires from a breadboard to a protoboard is this possible? or is there a way to prototype w/o soldering

thanks in advance

One time I used one of those little breadboards that Parallax sells and stuck in onto a Protoboard.
It has a sticky back, making it semi-permenant..

But, you're always going to have to do a little bit of soldering to run wires from the Protoboard to the breadboard...

The Propeller Platform already has headers soldered on, so you could just use jumper wires if you had that board instead...

Hi speewave,

surely you can use a protoboard USB together with a breadboard. To get a proper connection on the protoboard-side - as far as I know - you have to solder.

I'm not sure if I understand right what you mean by "is there a way to prototype without soldering.

You can plug a propeller-DIP40-chip into a 40DIP-socket and put this together with chrystal, EERPOM and prop-plug on a breadboard.
This product http://www.parallax.com/Store/Microcontrollers/PropellerKits/tabid/144/ProductID/415/List/0/Default.aspx?SortField=ProductName,ProductName
Propeller Education Kit - 40 pin DIP Version does exactly this.

As long as your circuit does not use really high frequencies (I guess more than 1MHz) everything should run on a bread-board too.
Exception the delta-signa-ADC. This circuit works only reliable with a NON DIP-40-package and really short wires.

But f.e. an MCP3208-ADC runs without any problems on a breadboard.

best regards

Stefan

ok thanks for your help!

I already own that protoboard so going out and purchasing another board isn't what i would care to do ...

by "is there a way to prototype without soldering." i meant for the board, like if i could insert a wire to the protoboard and to the breadboard with out soldering.

but thanks again

Two years ago at UPENE they gave away a protoboard with a mini breadboard. Here's OBC's post on how to set it up if you are interested. http://forums.parallax.com/showthread.php?115444-I-got-a-free-kit-at-the-Expo.-What-do-I-do-with-this-!&highlight=protoboard

Solder a connector to the board, run wires to it from the Propeller and solder those. You can then connect it to things without soldering.

There is a solution..

I own a Proto Board too and wanted to connect wires without soldering. The board brings out the port lines from the surface mount propeller chip to plated through the board holes. What you are asking for is a connector to join these plated holes to wires which can then route to solderless breadboards for example.

Some companies sell tubes of conductive solder - in squeeze tubes which do not need heat to make a joint - it's more like a glue paste to be applied.

Are there tiny solder-less adjoining connectors for holes this small? I don't know of any. But I do know of a technique to directly join the wire to the through-the-board plated hole.

When routing a wire from the LED mod described in this large thread
http://forums.parallax.com/showthread.php?124495-Fill-the-Big-Brain&p=977025&viewfull=1#post977025
(see LED mod) I used a single strand wire bared at the end about 1/8th-inch or less and pushed it into the circuit hole. Fortunately for our purposes, one wire roll was slightly too big. After pushed in, it would not come out (easy).

What this did was provide a firm electrical connection without soldering. As long as the wire is stationary and well joined (the protruding wire stub can be trimmed and folded over or splayed to further provide board contact from the back side, this method should work. I don't have an exact gauge number so you would need to try some different sizes to find the right one. This technique was tested and working on one PPPB with a power light converted to a data LED.

I would suggest using a small piece of tape to affix any considerable length of the wire as it is routed to the solderless breadboard to minimize an electrical noise due to potential minute movements.

@speewave,

This document is becoming dated, but should help.

I haven't tried them but these maile headers from Sparkfun may work with female-male jumpers.

If you wrap the stripped end of solid core 22 AWG wire (the type used for breadboarding) through one of the through holes attached to the prop pins and one of the adjacent holes on the Prop Proto board you can get a usable connection with out any soldering, I some times do this.

I went to the parts store today and was surprised to learn there are tiny connectors that fit into the plated-through holes on printed circuit boards. The ends of these connectors attach to a wire which is what you want for breadboard connections. A mail order store that supplies Chinese parts and components should stock these.
