take a look at http://www.cypress.com/psoc5lp/ -> Kits -> Third party kits. I assume the FreeSOC is the nearest kit you're searching for, but it costs a lot more than 10$.
You want something like that, but without the onboard debugger, right?
Schartboard had a version with the 5LP for $15 back a year or so ago.. they still have the bare boards, but you have to provide the 5LP..
Maybe Neal will run another special on these again :)
I want basicly the same thing as the -049 psoc4 devboard, built in usb interface/bootloaderthingy..
currently there is a schmart board especial where you can get a populated psoc5lp board with a discount.
The PSOC5LP devices are more expensive than psoc4 so I doubt you can get $10 boards with a psoc5 in them.
The pioneer board with a 5LP and a PSOC 4 is pretty cost effective
at $ 25.00 http://www.cypress.com/?rid=77780
Dual use (use both processors independently if you wish)
Note the primary drawback is limited pinout of the 5LP on the board, but then there
is nothing holding you back from using the 4 as an I/O slave and the 5LP for all its
horsepower. And its Arduino pinout great cheap expansion capability.
I didnt actually think of that!, plus I was wanting to get one of those anyway!
But beware! The PSoC5LP can only be programmed with a MiniProg 3 or something adequate which will stress your purse additionally.
