Overview
TinyPEPPER is an open-source printed circuit board by fishpepper, from the fishpepper/tinyPEPPER repository on GitHub. It is a 2-layer board of 20 × 22.3 mm with 97 parts on 82 nets, routed with 1,243 tracks and 69 vias.
It is built around the IRLML2244 and IRLML6244. Its parts include 28 resistors, 9 capacitors and 4 ICs. It belongs with the robots and motor control boards and the Silicon Labs (EFR32, EFM) boards of this library.

README.mdtinyPEPPER -- a tiny and lightweight 4in1 BLHeli_S ESC
My approach to build a small and lightweight ESC.
See http://fishpepper.de/projects/tinyPEPPER for more details.
This thing is TINY! The outer dimensions are 20x20mm with a 16mm hole-to-hole spacing. It runs BLHELI_S
Key features:
- 16x16mm hole-to-hole spacing
- 1.2g (!)
- BLHeli_S with DSHOT300
- 1S only (really!)
This work is published under the CERN open hardware license v1.2. Feel free to use the design - but make sure to give proper credit and release all modifications under the same license! See LICENSE.txt for details!
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 TinyPEPPER PCB?
It measures 20 × 22.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TinyPEPPER use?
97 parts, built around the IRLML2244 and IRLML6244. 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 TinyPEPPER KiCad files?
From the fishpepper/tinyPEPPER repository on GitHub, at the commit this page was made from: the board is tinyPEPPER.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyPEPPER design in my own project?
Its repository states no licence, so its author keeps all rights: ask fishpepper before reusing the design.
