Overview
Malenki is an open-source printed circuit board by MarkR42, from the MarkR42/malenki-esc repository on GitHub. It is a 2-layer board of 23.7 × 25.5 mm with 30 parts on 26 nets, routed with 323 tracks and 24 vias.
It is built around the ATTINY1614-SSN, RZ7899 and ME6210A50PG. Its parts include 7 resistors, 7 connectors, 6 capacitors, 5 ICs and 2 diodes. It belongs with the robots and motor control boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.mdMalenki-ESC
Malenki-ESC is a DC electronic speed controller for small robots. An ESC converts signals from e.g. a radio receiver into higher current pulses for motors.
- Power: 6-13 volts, from a lipo 2S or 3S pack
- Three reversible DC motor drivers: two for tank-steering and one for "weapon"
- Single wire input, supporting either PPM or serial protocols s-bus or i-bus
- 5v power output / regulator / "BEC" to power a radio (not suitable for a large servo)
- Battery level monitor
- Some status LEDs
- Failsafe operation (turns off motors if signal lost)
The main focus is on a very tiny footprint to fit into small devices.

Questions
How big is the Malenki PCB?
It measures 23.7 × 25.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Malenki use?
30 parts, built around the ATTINY1614-SSN, RZ7899 and ME6210A50PG. 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 Malenki KiCad files?
From the MarkR42/malenki-esc repository on GitHub, at the commit this page was made from: the board is hardware/malenki/malenki.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Malenki design in my own project?
Its repository states no licence, so its author keeps all rights: ask MarkR42 before reusing the design.
