It measures 70 × 100 mm and has 2 copper layers, 1.67 mm thick.
48 parts, built around the MAX6675ISA+, TCMT1100 and WS2812B-5050RGB. 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 FHafting/BREAD repository on GitHub, at the commit this page was made from: the board is [SLC_RLHT] Relay Heating Element Controller/Hardware/BREAD_Slice.kicad_pcb and its schematic [LOAF_ESPTP] ESP32 Thing Plus Controller/Hardware/BREAD_Loaf.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask FHafting before reusing the design.
