On the other, you have size and expense. Plus parasitic capacitance, of about 2-3pF row to row, and 20pf rail to rail.

Building with Solderless Breadboards typically means using push-wires to make MCU, Module and Breadboard connections. Your Project eventually grows a wiring rats-nest. You might think there’s no way around this.

But what if you could use Custom Cables to make those Header-like connections? That rats-nest would shrink or perhaps even disappear! Project reliability and appearance would improve immediately.

Well, you can make those connections using Custom Cables of exact length and wire count! Its accomplished using thru-hole Headers, a Wire-Wrap tool and some 2-side sticky tape. The technique is low cost and easy to learn! Check this out…

Many a budding electronics maker got their start not with a soldering iron, but with the humble breadboard. With its push connections, the breadboard enables electronics experimentation without requiring the specialised skill of soldering or any dangerous hot tools. What it lacks is a certain robustness that can make all but the simplest projects rather difficult to execute. [Runtime Micro] have shared a few tips on making things just a little more robust, however.

The fundamental principle behind this process is replacing point-to-point jumper wires with custom cables, made using 0.1″ pitch headers and wire-wrapping techniques.

Permanent Solderless Breadboard?

The Permanent Solderless method combines Breadboards, thru-hole Headers and Wire-Wrap to make resilient electronic projects. Because flimsy push-wires (also called jumpers) are eliminated, circuits are more tolerant of impact and vibration. And that translates into long lasting builds with decent reliability.

Are Thru-Hole Headers Suitable for Wire Wrap?

Yes! Thru-hole Headers have tenth-center spacing and square .025 inch posts. They can be inserted (with care) into AWG #21-22 compliant Breadboards.

I was using this piece of breadboard for choosing component values for a simple circuit. I’d bought it some time back from a typical Chinese ebay seller. While testing the circuit I just couldn’t get it to work. I double and triple checked all the connections and swapped components, but it still didn’t work. It was only when I actually started metering it out that I discovered that the breadboard does not have continuous bus strips at the top and bottom. Instead they are divided into three sections each with no markings on the front to indicate that.
