FPC
About the FPC PCB
FPC is an open source PCB design by kholia, published on GitHub. It is a 2-layer board measuring 27.1 × 28.7 mm, with 9 components from 8 distinct parts.
Other key parts include the LM2596S-ADJ. By type, the board carries 3 capacitors, 2 diodes, 2 resistors, 1 IC and 1 inductor.
From the project
HF-PA-v10 ;) Is this the end of the search for a 5W Digital PA? HF-PA-v10 is now a rugged 10W PA! We also do 100W+ now ;)

FPC: common questions
How big is the FPC PCB?
The FPC measures 27.1 × 28.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the FPC?
9 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the FPC design files?
From the kholia/HF-PA-v10 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FPC design in my own project?
The repository has no license, so all rights stay with kholia. Use it as a reference, and ask the author before reusing the design.
