tomasmcguinness/matter-esp32-mbus-adapter
An ESP32-C6 adapter board for wired M-Bus (EN 13757) meters, with firmware examples that expose meter readings to a Matter fabric over Thread.



It measures 150 × 100 mm and has 4 copper layers, 1.6 mm thick.
200 parts, built around the BQ25858QWRRVRQ1, CSD19506KTT, MIC29152WU and SS14. 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 usern4mehere9/LVPSU repository on GitHub, at the commit this page was made from: the board is LV_Regulator/LV_Regulator/LV_Regulator.kicad_pcb and its schematic LV_Kontrola_Main/LV_Kontrola/LV_Kontrola/LV_Kontrola_Main.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).
