Diy shift indicator: common questions

What microcontroller does the Diy shift indicator use?

The Diy shift indicator is built around the PPTC111LFBN-RC, from the AVR/Arduino family.

How big is the Diy shift indicator PCB?

The Diy shift indicator measures 99 × 68 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Diy shift indicator?

27 components, from 20 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 Diy shift indicator design files?

From the Rav4s/diy-shift-indicator 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 Diy shift indicator design in my own project?

Yes, under the terms of its GPL-3.0 license, which Rav4s chose for the repository.

Can I test firmware for the Diy shift indicator 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.
