Bill Of Materials
The board is manufactured through JLCPCB's PCBA though not complete as the ESP32-S3-WROOM-1 and header pins are going to be hand-soldered.
For the breakdown of the board's individual components, check check Components.
For the breakdown of the PCBA components, check Components.
For the breakdown of the entire cost check (PCBA + ESP32 + Connector pins + resistor) check BOM or look below.

Questions
How big is the TrlBoard PCB?
It measures 56.5 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TrlBoard use?
47 parts, built around the CH340C, ESP32-S3-WROOM-1-N8, BQ24072RGTR and TPS63060DSC. 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 TrlBoard KiCad files?
From the TrlRizu/TrlBoard repository on GitHub, at the commit this page was made from: the board is TrlBoard.kicad_pcb and its schematic TrlBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TrlBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask TrlRizu before reusing the design.
