Hpil: common questions

What microcontroller does the Hpil use?

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

How big is the Hpil PCB?

The Hpil measures 49.9 × 78.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hpil?

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

Where can I download the Hpil design files?

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

Can I use the Hpil design in my own project?

Yes, under the terms of its AGPL-3.0 license, which gIzFer chose for the repository.

Can I test firmware for the Hpil 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.
