HeaterMeterPI: common questions

What microcontroller does the HeaterMeterPI use?

The HeaterMeterPI is built around the ATmega328P, from the AVR/Arduino family.

How big is the HeaterMeterPI PCB?

The HeaterMeterPI measures 94.6 × 46.1 mm and is 1.6 mm thick.

How many components are on the HeaterMeterPI?

63 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the HeaterMeterPI design files?

From the CapnBry/HeaterMeter repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the HeaterMeterPI design in my own project?

Yes, under the terms of its MIT license, which CapnBry chose for the repository.

Can I test firmware for the HeaterMeterPI 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.
