About the Slider potentiometer breakout qwiic hardware design
Slider potentiometer breakout qwiic hardware design is an open source AVR/Arduino PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 86 × 22 mm, with 15 components from 8 distinct parts.
Its main chip is the ATTINY404-SSNR, from the AVR/Arduino family. By type, the board carries 4 relays, 3 capacitors, 3 resistors and 1 IC.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
Hardware design, BOM, gerbers and 3D files for Slider-potentiometer-breakout-qwiic designed by Soldered Electronics.
Potentiometers are well known all around, and the sliding potentiometer is just one of its versions. You’ve probably seen it in some music equipment, and now you have the chance to add it to your project!
This board has easyC connector. Thanks to easyC ecosystem, this board can be connected using off-the-shelf cables, without soldering. Controlling the is as simple as it gets, too.
