VERSION 1.9 J120 (38198-X)
I2S (J16)
This is a 6 pin connector with 1.25 mm pitch. All signals are covered from 1.8V (TX1) to 3.3V (connector) with
a bi-directional level converter. The data direction is automatically determined by the level converter.
J120 rev 1, 2, 3 and 4:
J120 rev 5 (38198-5) and newer:
SPI/I2C (J13)
This is a 10 pin connector with 1.25 mm pitch.
Note: J120 rev 1, 2, and 3: pin 8 and pin 9 have 1k pullup (rev 4 and newer: 10k)
