- The OpenWrt device table warns against buying 8 MB flash / 64 MB RAM devices if you want an up-to-date, secure build.
OpenWrt targets network devices and other small embedded boards. Its supported-devices guidance lists 8 MB flash and 64 MB RAM as the bare minimum, but explicitly recommends 16 MB flash and 128 MB RAM for stable operation with current, secure releases.
Check the device table for your exact hardware before you flash anything.
