It measures 37.7 × 37.7 mm and has 4 copper layers, 4.69 mm thick.
68 parts, built around the ESP32-PICO-V3, 2450FM07D0034T, RFX2401C and AP2138N-2.8TRG1. 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 AnyLeaf/elrs-hardware repository on GitHub, at the commit this page was made from: the board is kicad files/dual radio pcb.kicad_pcb and its schematic kicad files/dual radio schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
