Overview
Biot node is an open-source printed circuit board by jonkster, from the jonkster/biot2 repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 41.7 × 58.7 mm with 17 parts on 23 nets, routed with 155 tracks and 5 vias.
It is built around the ATSAMR21B18-MZ210PA and LP2985-33DBV. Its parts include 5 connectors, 2 capacitors, 2 resistors, 2 ICs and 2 diodes. It belongs with the SAM D and SAM boards of this library.

Questions
How big is the Biot node PCB?
It measures 41.7 × 58.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Biot node use?
17 parts, built around the ATSAMR21B18-MZ210PA and LP2985-33DBV. 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 Biot node KiCad files?
From the jonkster/biot2 repository on GitHub, at the commit this page was made from: the board is hardware/biot-node.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Biot node design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).

2B is the "definitive" version so all code going forward is designed for that version of the board. Minor hardware differences mean that code for 2.0 may not work on 2.0B without tweaks (mostly related to ram banking)
