Pseudonymous Swedish maker “Debinix” has put collectively a compact breadboard-friendly breakout designed to supply fast and straightforward affirmation of inputs and outputs with out having to fiddle with discrete parts: the TinyLedSwitch.
“The TinyLedSwitch Breakout Board eliminates the necessity to cram in extra resistors, LEDs, and flimsy switches in your breadboard,” Debinix explains. “As a substitute, 4 colourful pink, yellow, inexperienced, and blue diodes point out the GPIO state. Use the Panasonic light-touch switches to tug down a microcontroller enter. The board works with any fashionable microcontroller or the Raspberry Pi. The optionally 90 levels pin-headers enable mounting it both horizontally or vertically.”

The thought is easy: a single-unit board, which replaces two inputs and 4 outputs, as a fast approach to verify that the software program facet of your mission is working as-expected. Whereas designed primarily for breadboard use, angled headers enable for both facet of the circuit to be related through flying wires as a substitute — very best for one thing just like the Raspberry Pi 4, whose general-purpose enter/output (GPIO) header is pre-populated with male pins.
The switches are designed to be used with the built-in pull-down resistors constructed into most Arduino and suitable microcontroller boards, however for these trying to interface with one thing missing built-in resistors there is a secondary mode: “Join the VCC [pin] to the breakout boards, the pin marked 3-5V, to tug up the voltage through a ten kOhm resistor,” Debinix explains.
The boards are actually obtainable fully-assembled through the Debinix Workforce Tindie retailer at $5.25 every; design information can be found on GitHub beneath a reciprocal Inventive Commons Non-Industrial Share-Alike 4.0 Worldwide license.
