Vswr meter: common questions
What microcontroller does the Vswr meter use?
The Vswr meter is built around the Teensy4.0, from the NXP family.
How big is the Vswr meter PCB?
The Vswr meter measures 65 × 70 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Vswr meter?
64 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the Vswr meter design files?
From the F6ITU/vswr_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 Vswr meter design in my own project?
The repository has no license, so all rights stay with F6ITU. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Vswr meter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
