Insay COB modul di drayva IC de sidɔm pan PCB, ɛn dɛn kin trit da bɔd de lɛk smɔl pas kyaria fɔ di drayv sɛrkyut. Bɔt luk di eria we lɛf, ɛn gud tin kin apin: dɛn kin fit MCU, wit rial-taym klok, flash, tɛmpracha sɛnsa, baklayt drayva ɛn lɛvɛl shifta; ivin sɔm simpul periferik sɛrkyut dɛn kin fold in. Di mɔdyul de go frɔm displei kɔmpɔnɛnt to displei kɔntrol bɔd.
