Adguard is very powerful software but why not install it a mifi?

I tried and got the results below.

AdGuardHome

Status: installed failed

Stdout: Installing AdGuardHome (0.103.3-1) to root…

Stderr: Collected errors: * verify_pkg_installable: Only have 2204kb available on filesystem /overlay, pkg AdGuardHome needs 6582 * opkg_install_cmd: Cannot install package AdGuardHome.

Is there a way to install it??

Is there any way to use SD memory as storage??

Adguard is powerful, but MiFi’s CPU is not.

The lowest specs for Adguard is AR750s. Just OK to run it.

oh… cpu loads…

Thanks.
