Life hack: since there are stretching lines inside the Wiren Board controller, after connecting it to the bus line A voltage will be greater than b by about 0.5 V. Therefore, connecting peripherals you can easily determine the bus line by the voltmeter. But, of course, color coding of conductors is more preferable.
