Plc: common questions

What microcontroller does the Plc use?

The Plc is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Plc PCB?

The Plc measures 129 × 137.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Plc?

110 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Plc design files?

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

Can I use the Plc design in my own project?

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

Can I test firmware for the Plc 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.
