My Turris Omnia arrived today!

Blinky Lights

The RGB LEDs can be controlled by sysfs, the "A" and "B" ones are available as:

/sys/class/leds/omnia-led:user1
/sys/class/leds/omnia-led:user2

In the picture, I set user1 to red and user2 to green with these command line arguments:

echo -n 0 >/sys/class/leds/omnia-led:user1/autonomous
echo -n 255 0 0 >/sys/class/leds/omnia-led:user1/color
echo -n 255 >/sys/class/leds/omnia-led:user1/brightness
echo -n 0 >/sys/class/leds/omnia-led:user2/autonomous
echo -n 0 255 0 >/sys/class/leds/omnia-led:user2/color
echo -n 255 >/sys/class/leds/omnia-led:user2/brightness

Looks like there's a stm32f030 (marked U21 on the schematic) that drives the LEDs with a custom firmware.

There's a file "trigger" that will let you trigger them based on some event (wifi activity, disk activity, network state, etc). See the linux LED documents for more details. There's also some support for changing LED settings in LuCI under System > Rainbow and System > LED Configuration

WiFi

I had to switch my country code under the LuCI interface at Network > Wireless > (radio 0/1) > Advanced Settings > Country Code. I setup both 2ghz and 5ghz and ran some speedtests on my Nexus 6P (supports 802.11ac 2x2).

These wifi tests were done in the same room. LuCI was showing "-46 dBm signal / -101 dBm noise" and "866.7 Mbps" RX rate, which is the max for 2x2 80MHz wifi.

Wired

I have 300M/20M internet, so this is a good result.

Misc

There's an ATSHA204 security eeprom on the i2c bus

There are headers with a variety of GPIO/SPI/UART/I2C pins.

DNS

Because the default is to use knot resolver, the default *.lan hostnames from dnsmasq aren't available.

Summary

Upsides: 7GB free space on an openwrt router is luxurious, more rgb blinky lights = more better, uses about 7 watts, uses openwrt out of the box, 3x3 802.11ac hardware.
