Overview
TinyPEPPER2 is an open-source printed circuit board by fishpepper, from the fishpepper/tinyPEPPER2 repository on GitHub. It is a 4-layer board of 22.3 × 22.3 mm with 163 parts on 100 nets, routed with 1,859 tracks and 108 vias.
It is built around the AP131-30WG, BC847 and UT6MA3TCR. Its parts include 80 resistors, 20 capacitors and 5 ICs. It belongs with the robots and motor control boards and the Silicon Labs (EFR32, EFM) boards of this library.

README
README.mdtinyPEPPER2 -- a tiny and lightweight 4in1 BLHeli_S ESC -- 2S edition
My approach to build a small and lightweight ESC.
See http://fishpepper.de/projects/tinyPEPPER2 for more details.
As my previous tinyPEPPER 1S design, this thing is TINY as well! The outer dimensions are 20x20mm with a 16mm hole-to-hole spacing. Of course it also runs BLHELI_S.
Key features:
- 16x16mm hole-to-hole spacing
- 1.4g (!)
- BLHeli_S with DSHOT300
- 1S or 2S operation
- 4.8 A continous current

THIS COMES WITH NO WARRANTY! BUILD, FLY, AND USE AT YOUR OWN RISK!
Build your own
Make sure to init the git submodule for the libraries in the kicad_misc directory by calling git submodule init && git submodule update. You will have to use a recent kicad version, i used the commit #efdfaeb when i designed this circuit board. Older versions will probably not work.

Questions
How big is the TinyPEPPER2 PCB?
It measures 22.3 × 22.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TinyPEPPER2 use?
163 parts, built around the AP131-30WG, BC847 and UT6MA3TCR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TinyPEPPER2 KiCad files?
From the fishpepper/tinyPEPPER2 repository on GitHub, at the commit this page was made from: the board is tinyPEPPER2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyPEPPER2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask fishpepper before reusing the design.
