I was pretty excited when I learned that Texas Instruments has a line of cheap & open-source development tools for their MSP430 microcontroller family (10 years ago they only offered ridiculously overpriced proprietary tools). They apparently created this new line of programming hardware back in 2010, so I ordered one of their Launchpad boards the other day, which is a MSP430F5529 evaluation board AND an EZ-FET Lite programmer all in one.
It was seriously cheap, really. $12.99 USD including shipping (and there’s a cheaper one for $9.99). This is insane considering that their traditional devkits cost over $200.
As I said before, this board not only has a MSP430 processor you can play with (and attach tons of modules, sensors, etc in a very Arduino-like fashion) but also has and on-board programmer and debugger that can be “isolated” and used to program any external MSP430 microprocessor with the Spy-bi-Wire (SBW) technology.
