I ran across mention of this development board from TI being priced at only $5, though this article:
http://www.wired.com/geekdad/2012/11/a-13-arm-single-board-computer/ says it is $13. Either way, it is likely priced at below cost, as the micro itself sells for nearly $5 in 1K quantities and the board has 2. This board has an 80MHz 32-bit ARM Cortex M4 microcontroller, 256KB Flash, 32KB SRAM, 2KB EEPROM, dual 12-bit ADC, and 43 GPIO pins. And like most modern dev boards, it interfaces via USB. TI supplies a proprietary toolchain, but apparently there are open source alternatives. Not a particularly small looking board, so might not be a good choice if you are looking to embed the dev board into a space constrained project. While it's cheap, you can get Arduinos for around $10 to $15, and will undoubtedly find a larger community of developers, so an Arduino is probably the better choice for a one-off hobby project. See also: http://dangerousprototypes.com/2012/10/01/review-of-the-stellaris-launchpad/ for a briefer intro (and better photo), followed by some discussion about the toolchain. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
