Current sense: common questions

What microcontroller does the Current sense use?

The Current sense is built around the Arduino, from the AVR/Arduino family.

How big is the Current sense PCB?

The Current sense measures 104 × 104 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Current sense?

17 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Current sense design files?

From the MadsRudolph/62768-energy-system 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 sense design in my own project?

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

Can I test firmware for the Current sense 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.
