Communication buses

MOSI

Master Out, Slave In

SPI data wire from controller → chip.

How it looks

Real geometry: CORE3588 copper, drawn from our board file (top and bottom layers; this net in amber)

MOSI on CORE3588 (amber): net IMU_MOSI.

1The motion sensor U11 at this end...
2...to the computer module socket. This one wire is MOSI: data from the module to the sensor.

MOSI is one wire of an SPI bus; the others are SCK, MISO, CS, INT.
