This section describes how specific components operate on the LS425 and LS445.
On-Board Switch / SVC Button
The on-board switch is connected to the GPIO02, which is pulled low when the service (SVC) button is pressed. Conversely, a pull-up on the button normally sets the GPIO02 to be pulled high.
Reset Switch / GPIO Button
The Reset button is connected to the reset circuit. Pressing the reset button will send an initial signal to the system software and holding the reset button low for approximately four seconds will cause a hard reset.
MicroSD Slot
The LS425 and LS445 have one MicroSD slot, which supports transfer modes up to UHS-1 DDR50 (50MB/s). There is no inherent limit on the storage capacity of microSD cards used with the player.
Wireless Module
The optional WiFi module also has Bluetooth functionality.
