Any idea what is wrong?

You cannot install kernel modules from openwrt repositories with our image. Even the kernel version match, the kernel magic won't. The solution is either build kernel with the modules that you need or you can use image from OpenWRT team:
https://downloads.openwrt.org/chaos_calmer/15.05.1/ramips/rt305x/openwrt-15.05.1-ramips-rt305x-olinuxino-rt5350f-evb-squashfs-sysupgrade.bin

or

https://downloads.openwrt.org/chaos_calmer/15.05.1/ramips/rt305x/openwrt-15.05.1-ramips-rt305x-olinuxino-rt5350f-squashfs-sysupgrade.bin

If you use the prebuild image, then installing kernel modules with opkg will be ok.
