PowerMeter2025: common questions

What microcontroller does the PowerMeter2025 use?

The PowerMeter2025 is built around the ATmega328PB-A, from the AVR/Arduino family.

How big is the PowerMeter2025 PCB?

The PowerMeter2025 measures 101.3 × 23.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PowerMeter2025?

52 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the PowerMeter2025 design files?

From the papurika37/KUBTSS_Board25 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PowerMeter2025 design in my own project?

The repository has no license, so all rights stay with papurika37. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PowerMeter2025 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.
