It uses the MCP73871 - USB/Solar panel charger and very nice TPS63031 Buck-Boost Converter. Main benefits of the board is small size and possibility to run literally forever from one small single cell LiPo battery.
It's necessary to burn bootloader with ISP before RFM95W module is soldered.

Questions
How big is the LoRaNode PCB?
It measures 43 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoRaNode use?
59 parts, built around the ATMEGA328P-AU, MCP73871EV, RFM95W-868S2 and TPS63031DSK. 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 LoRaNode KiCad files?
From the cernohorsky/LoRa-Node-Solar repository on GitHub, at the commit this page was made from: the board is LoRaNode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRaNode design in my own project?
Its repository states no licence, so its author keeps all rights: ask cernohorsky before reusing the design.
