Service Button
The Service (SVC) button provides a dedicated GPIO button (GPIO12) for the OS. Pressing the SVC button pulls the pin low. Conversely, releasing the button pulls the pin high.
Reset Button
The Reset button is connected to the reset circuit. Pressing down the Reset button will send an initial signal to the system software, and holding the reset button low for approximately 4 seconds will cause a hard reset.
System Memory
The LS424 features 2GB of DDR4-2400 DRAM.
microSD Slot
The LS424 has 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 LS424 has an internal M.2 slot for installing a compatible wireless module. The M.2 wireless module connects via cable to an external, attachable wireless antenna.
