What it is

Breaks the TMF8829 sensor bus out onto a 32.000 x 32.000 mm machine-pin datum: 18 contacts, all on the 2 mm grid. Both I²C and SPI reach the contacts; the flight controller uses SPI. /SCL and /SDA reach MC9/MC8.

The board, section by section

Datum

All contacts sit on the 2 mm grid; the datum is exactly 32.000 x 32.000 mm.

Interface

Carries the sensor's SPI (20 MHz max) and I²C to the machine contacts. Nothing may drive SCL low before firmware issues BL_CMD_I2C_OFF.
