Additional Hardware Info
The OpenWRT site has additional information about this device including the location of UART and other exposed GPIO connections. https://openwrt.org/toh/buffalo/ls421de
It also links to an OpenWRT install process which I have never attempted. If you do choose to look into it note that it involves re-flashing the NAND and modifying the bootloader which may require soldering a serial connection to the board to undo.
