Voltage Meter: common questions
What microcontroller does the Voltage Meter use?
The Voltage Meter is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the Voltage Meter PCB?
The Voltage Meter measures 28.1 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Voltage Meter?
21 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Voltage Meter design files?
From the LuizFernandoOliveira/Voltage_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 Voltage 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 Voltage 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.
