About the Higher lower PCB

Higher lower is an open source AVR/Arduino PCB design by oskitone, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 63.5 × 38.1 mm, with 14 components from 12 distinct parts.

Its main chip is the ATTINY85V-10PU, from the AVR/Arduino family. By type, the board carries 3 switches, 2 capacitors, 2 resistors, 1 IC, 1 connector and 1 battery holder.

It belongs with the audio designs in this gallery.

Higher lower: common questions

What microcontroller does the Higher lower use?

The Higher lower is built around the ATTINY85V-10PU, from the AVR/Arduino family.

How big is the Higher lower PCB?

The Higher lower measures 63.5 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Higher lower?

14 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Higher lower design files?

From the oskitone/higher_lower repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Higher lower design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which oskitone chose for the repository.

Can I test firmware for the Higher lower without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
