Split-Flap-Display: common questions

What microcontroller does the Split-Flap-Display use?

The Split-Flap-Display is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Split-Flap-Display PCB?

The Split-Flap-Display measures 97.8 × 71.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Split-Flap-Display?

33 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Split-Flap-Display design files?

From the oli4wolf/Split-Flap-Display repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Split-Flap-Display design in my own project?

Yes, under the terms of its GPL-3.0 license, which oli4wolf chose for the repository.

Can I test firmware for the Split-Flap-Display 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.
