6xUSB PowMet hub: common questions

What microcontroller does the 6xUSB PowMet hub use?

The 6xUSB PowMet hub is built around the ATMEGA32-M, from the AVR/Arduino family.

How big is the 6xUSB PowMet hub PCB?

The 6xUSB PowMet hub measures 201.4 × 150.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 6xUSB PowMet hub?

97 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 6xUSB PowMet hub design files?

From the aleksejm/6xUSB-Power-Meter repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 6xUSB PowMet hub design in my own project?

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

Can I test firmware for the 6xUSB PowMet hub 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.
