Antenneschalter V2: common questions
What microcontroller does the Antenneschalter V2 use?
The Antenneschalter V2 is built around the PE42412A-X, from the Silicon Labs family.
How big is the Antenneschalter V2 PCB?
The Antenneschalter V2 measures 58.1 × 65 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Antenneschalter V2?
63 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Antenneschalter V2 design files?
From the KhanKudo/diplomprojekt repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Antenneschalter V2 design in my own project?
The repository has no license, so all rights stay with KhanKudo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Antenneschalter V2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
