Enc panel: common questions

What microcontroller does the Enc panel use?

The Enc panel is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Enc panel PCB?

The Enc panel measures 68.6 × 89.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Enc panel?

30 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Enc panel design files?

From the mar0x/pq-4 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Enc panel design in my own project?

The repository has no license, so all rights stay with mar0x. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Enc panel 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.
