Yes — that's a core feature. Modules share one I²C bus and differ only by address. Add circuits by adding modules on the same two wires, behind one host — no extra microcontroller, no serial-port juggling. For coherent energy across modules, one broadcast latch snapshots them all on the same instant. See the builds: whole panel on one ESP32 and multi-module Arduino bus.
