phpkadir/KiCad-Sensorless-BLDC-ESC2I designed this pcb because I want to be able to try different microcontrollers as part of Electronic Speed Controller projects. It can be used with the microcontrollers those don't have the internal comparator capability.
BLDC SensorlessWithLM339 is an open-source printed circuit board by phpkadir, from the phpkadir/KiCad-Sensorless-BLDC-ESC repository on GitHub, published under the MIT licence. It is a 2-layer board of 99.1 × 99.1 mm with 55 parts on 38 nets, routed with 328 tracks and 57 vias.
It is built around the IR2101PBF and LM339N. Its parts include 24 resistors, 9 diodes, 8 capacitors, 6 transistors and 4 ICs. It belongs with the robots and motor control boards of this library.
I designed this pcb because I want to be able to try different microcontrollers as part of Electronic Speed Controller projects. It can be used with especially the microcontrollers those don't have the internal comparator capability.
I ordered the version 0.3 and will test it when it arrives.
I made some mistakes about connections of the mosfet circuits. I will fix those mistakes in the next update.

It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
55 parts, built around the IR2101PBF and LM339N. 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.
From the phpkadir/KiCad-Sensorless-BLDC-ESC repository on GitHub, at the commit this page was made from: the board is BLDC_SensorlessWithLM339/BLDC_SensorlessWithLM339.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
