AtomSoftTech has a convenient little board to make it easy to connect a tact switch to a breadboard:
AtomSW on Tindie
What is it?
A button you can be glad to have.
Why did you make it?
There isnt a small breadboard-able button out there with the features on this one.
What makes it special?
You have a selectable Pull-Up or Pull-Down and selectable High Output or Low Output. Using simple solder jumpers you can select between Pull up or Pull Down and what is the output of the button. All in a TINY PCB takinng almost no space on your PCB. No need to wire anything its breadboard friendly. Connects to the power rails and data side as well
Clovis Fritzen designed this Arduino-compatible, vertically-mountable board that exclusively uses through-hole components:
I personally love the concept of electronic boards connected in “slots” (vertically attached to a horizontal board), like most industrial-grade PLC’s or even our desktop’s expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!
The PCB is for sale on Tindie:
Vertically mountable Arduino – PCB only
This is an Arduno-Nano compatible controller that can be vertically mounted to bredboards and boards
UPDATE: Check out the new version with pull-up resistors
I designed this simple breakout board in KiCad to make it easier to put a rotary encoder on a breadboard. The KiCad symbol and footprint for the SparkFun rotary encoder was created by mcous on GitHub. I used an updated version with corrected pin numbering.
Here are the rotary encoders that I’ve verified to fit:
The design files are available on GitHub:
The board is shared on OSH Park:
Jakub Polonský created this solution to make breadboard prototyping safer for components:
adjustable and programmable electronic fuse especially designed for breadboards – a breadboard fuse, or BFuse
The trip current can be set from 50 mA to 1 A but it can measure current up to 6 A [..] It has reverse polarity protection (by P-FET), transient voltage suppressors both on its input and output and two LEDs for indication
Set current and actual current can be compared using ATTiny’s built-in comparator or sampled by the ATTiny’s ADC. Then, the microprocessor controls a P-FET switch that opens or closes the power supply
