VERSION 1.9

J120 (38198-X)

Micro SD card (J15)

Micro SD card reader (Amphenol 101-00660-68-6). SDCARD_WP (F20) = 0 (inactive).

Buttons (J12)

6 pin connector with 1.25 mm pitch (on the bottom side next to the green LED).

M.2 type M 2280 (J15)

J120 rev 1: this slot is non functional due to power limitations of the integrated 3.3V power supply.

J120 rev 2: this will be fixed by adding a 3.3V 3A power supply.

Form factor: 2242, 2260 or 2280 (22 x 80 mm)

Interface: four PCIe lanes for top performance (no SATA support)
