Mag encoder is an open-source printed circuit board by RealtimeRoboticsGroup, from the RealtimeRoboticsGroup/electrical repository on GitHub. It is a 4-layer board of 19.9 × 27.7 mm with 26 parts on 29 nets, routed with 321 tracks and 44 vias.
It is built around the MA732GQ, AP2120N-3.3TRG1 and SN74LVC7032ABQAR, with the MMSD4148T1G-MS among its other parts. Its parts include 8 resistors, 5 capacitors, 5 diodes, 3 ICs and 2 connectors.

Space on a PCB is usually at a premium. You can use this condensed version on the back of the board (Bottom Silkscreen):

If you want to signal that this is open-source hardware visually, it is common practice to add the Open Source Hardware Logo (a gear with a missing tooth) next to the license text. Most CAD libraries (like the SparkFun or Adafruit libraries) already have this logo as a "footprint" you can simply drop onto your board.

It measures 19.9 × 27.7 mm and has 4 copper layers, 1.6 mm thick.
26 parts, built around the MA732GQ, AP2120N-3.3TRG1, SN74LVC7032ABQAR and MMSD4148T1G-MS. 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 RealtimeRoboticsGroup/electrical repository on GitHub, at the commit this page was made from: the board is circuit-boards/mag-encoder/mag-encoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask RealtimeRoboticsGroup before reusing the design.
