It measures 50.1 × 88.2 mm and has 2 copper layers, 1.6 mm thick.
76 parts, built around the ATGM336H-5N31, SA818S-V, BME280 and BSS138. 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 custom-ds/ptFlex repository on GitHub, at the commit this page was made from: the board is ptFlex/ptFlex.kicad_pcb and its schematic ptFlex/ptFlex.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
custom-ds/ptSolar
Under the hood, the ptSolar runs on the same Microchip ATMega328p microcontroller that the other trackers have been using for years, although this board runs at a lower 3.3 volt level, and a slower 8MHz clock speed.
