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 84.4 × 36.8 mm and has 2 copper layers, 1.67 mm thick.
25 parts, built around the QTLP651C4TR. 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/mini-pdb-V2/mini-pdb.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.
