RadioShack was clearing out their MakerShed Netduino kits recently (well, I think 2 months ago by now) for $19.99.

That's why they have been popping up on eBay.

It's a great kit, comes with a lot of peripherals that alone are worth $20 retail.

I think we can safely exclude 100MHz and 2GHz, but you probably already knew that

500kHz looks pretty unlikely too ...

 

Does this help (towards the end of the post, under: "Bit toggling"):

It's not talking about Netduino in particular but the .Net Micro Framwork in general. But some good insights ...

 

"So basically, with a 100 MHz processor, you can usually do around 20 ?s wide pulses using managed code (about 25 kHz)."

 

Another similar discussion on the TinyCLR forum:

"72 MHz sounds very fast.
But I was surprised that outputting an alternating 0 and 1 via .NET code was so slow!
I got only 10 kHz."

 

 

So I am guessing it would be less than 10kHz, if your code runs on the Netduino Go and communicates the command to toggle a pin to the shield base over the go!bus protocol ...

You should be able to use one of the serial ports on the Netduino Go directly.
No need for the shield base.
But you'd need a cable that goes into the Go Port or a breakout board if you can find one:

PS: yes it is frustrating that it seems the Netduino Go doesn't seem to get any real software updates anymore, despite repeated "announcements".
