Here's a cheap way to convert that Model F-XT or make that 122-key terminal board programmable:

Looks a little different-- the reset button, for example-- from the ones I've seen.

It is intriguing because there's a huge gap in the market above for Pro Micro for a cheap controller for battleship boards and fullsize conversions that need more pins.

Fake.  Component layout doesn't match a Teensy++ 2.0  (which is what it's trying to be) and it's using the exact box shown on the counterfeit ID page.

Plus, it's from China.  Worth a couple bucks more to get it from PJRC or a certified reseller.

Too bad, that would be a good price. But it is certainly not a 2.0, which is what Soarer's firmware is based on.

So come to that realization. There are rabid coyotes running around. You don’t wait till you see one to go get your gun. Keep your gun handy, and every time you see one, you shoot one."

I'm not sure I know what you mean by "fake", or how important that is.

Of course I didn't think it was actually made by the original Teensy developer. They're not trying to conceal the fact that it's being made and sold from China. Apparently they've just built a Teensy 2.0 equivalent, the same way any experienced electronics hobbyist could—and they can offer it more cheaply because their costs are lower. Does it really matter, as it works the same?

Teensys use a custom bootloader which is smaller, so any firmware designed for the Teensy rather than the raw ATMega chip won't work on a fake.

Do you know it works the same?  Do you know the quality of the components and manufacturing of the hardware matches what PJRC makes?  Do you know if it has recent and correct firmware?

Teensy is a brand name, made by a specific company with a known reputation behind their product.   This might be "Teensy compatible" or "Teensy-like" but it's not a Teensy.

It might work fine.  It might not.  But it's not a Teensy.
