LIN VBAT
The LIN-bus positive reference. Supports systems operating from 4V to 24V.
• LIN1 VBAT: Pin is shared with device supply and shares the supply input protection circuit
• LIN2 VBAT: Tolerates voltage spikes up to 48V. Spikes above this can damage the interface
LIN Data
LIN-bus single-wire data line referenced to LIN VBAT.

0.3.3 Enclosure
The CANedge uses a robust aluminium enclosure - PDF drawings and 3D STEP files can be found in
the online documentation.
0.3.4 SD card
The CANedge uses an extractable SD-card to store device configuration and log files.
Warning:
Never extract the SD-card while the device is on. Remove power first and wait a few
seconds for the device to turn off.
0.3.4.1 File organization
The files stored on the SD-card are organized as illustrated by below example:
/
config-XX.XX.json
schema-XX.XX.json
device.json
