Current Meter: common questions

What microcontroller does the Current Meter use?

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

How big is the Current Meter PCB?

The Current Meter measures 23.5 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Current Meter?

10 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Current Meter design files?

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

Can I use the Current Meter design in my own project?

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

Can I test firmware for the Current Meter 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.
