Volt amp meter: common questions
What microcontroller does the Volt amp meter use?
The Volt amp meter is built around the PIC16F883-IP, from the PIC family.
How big is the Volt amp meter PCB?
The Volt amp meter measures 50 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Volt amp meter?
24 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Volt amp meter design files?
From the ApophisXIV/PCB-Desing repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Volt amp meter design in my own project?
The repository has no license, so all rights stay with ApophisXIV. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Volt amp meter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
