Since there are always questions that come up about what are the use-cases and applications of this thing. Here are a few more:
- Z-Wave security and penetration testing (Z-wave is used in smarthome automation and also newer home security systems like the Ring Security system). Z-Wave works in the 800-900 MHz bands. - SimpliSafe security and penetration testing (another very popular wireless security system that uses wireless motion sensors and magnetic door sensors). SimpliSafe works on 433 MHz (to basestation) and 315 MHz (from base station). - Security and pentetration testing of Zigbee (used in lots of applications including IOT, wireless sensor networks, industrial control, smarthome automation, etc). Zigbee works on 2.4 GHz (not covered in this product) but also works in the 800-900 MHz band which this product covers.
And shocker, many of these systems have known vulnerabilities. For those looking to get into security research, this would be a great first product, as it's much cheaper than the HackRF. There are likely more flaws to be discovered. The companies state these products are "safe" and "secure" but the burden of proof has already been laid at their feet.

$100 on Adafruit +S&H or $93 here w/ free S&H (and a 30 day wait)
Adafruit also has the official Great Scott antennas and a few other antenna options for anyone interested.

Are there any real advantages to this over an SDR?

Most SDR dongles cannot transmit, if that's what you mean by "SDR"

Very correct. Have an endorsement. I use an SDR in tandum with the YS1 making rfcat an easy life.

One of the things I hate about the DIY Tech scene is how there is a wide range of products that look interesting, yet the people that make these things never show any practical examples of what you can do with the device. All you ever get is a screenshot, a vague description and some specs. It would really help if these products had videos showing off some of the cool things that you can do if you purchase the device.

The hobbyist community does that for them at no expense in the natural course of the hobby itself, but companies tend to want to control their marketing materials. Linking to the 'blog pages and such where those hobby projects are documented and discussed would tend to make that difficult.

So to be clear, this does NOT come with the ANT500 antenna? Looks like the hak shop includes it for $130, and the antenna usually runs about $30, so this is like $10 off? Ok sure, I've been wanting to get one anyway lol

Could one of these units communicate with another one of these units? What kind of round trip latency would we be looking at?

It's an SDR (Software Defined Radio). i.e. you hook it to your computer and can arbitrarily interact with radio signals (sub 1Ghz). More info here: https://greatscottgadgets.com/yardstickone/

It's not an SDR. All demodulation is done in hardware on the chip. It supports ASK, OOK, GFSK, 2-FSK, 4-FSK, and MSK. Pick a frequency and a modulation that you want to listen to and it will spit out a bitstream. Software-defined radios sample the waveforms over the air and then spit that directly out to a host computer for processing in software.

This site sells them and has a couple videos on things you can do with them. Their forums usually have a lot of info too. https://hakshop.com/collections/wireless-gear/products/yard-stick-one

Since neither the description on Massdrop nor the GreatScottGadgets page made any reference to transmit power, I looked at the schematics and this is what I came up with:
- 10 dBm output from the CC1110, which is 10 milliwatts at 50 ohms. - That's passed to a SPF5043Z LNA MMIC, which has a ~18 dB gain - There would be a bit of loss in the SKY13385 switch and the LPF but let's just say they're negligable. - That totals out to a whopping 631 milliwatts of output
tl;dr: This is keyfob territory, not amatuer radio station territory. e.g. within a building or within the range of a car. Being that this radio will happily transmit in amateur radio 70cm band, it could be hooked up to a linear amplifier up to the legal limit (1500W, IIRC) as long as it's within the geographical limitations, e.g. stay the heck away from Canada). You'd need some sort of power-activated PTT but otherwise would work. There are better 70cm radios out there, considering this one only works with a few select data modes (admittedly at 500 kbps which isn't shabby).
Edit: I only briefly looked at this, if anyone comes up with a different number, I'll be happy to edit my post.
