INCREDIBLE customer service, a MUST for MCU programmers and robotics builders, accurate same day shipping, frequent sales, a user forum covering all of their products-you can actually TALK DIRECTLY WITH THEIR DESIGN ENGINEERS, FREE software downloads, Almost all manuals and technical information can also be either downloaded free or can be purchased in book form. There's also a TON of free educational and examples to download Their SX and Propeller MCUs are powerful, fast, versatile and can be programmed in multiple languages...Assembly, BASIC, C, FORTH plus a few more. These will blow away most MCUs, including the PIC. Available in both SMT and DIP versions The SX is an 8 bit RISC MCU that runs up to 75 MHZ current cost is $3.95. It is currently at end of life, but there are many thousands in stock The Propeller is an 8 core, 32 bit MCU (that's 8 separate 32 bit MCUs in 1 chip) speed is up to 80 MHZ I didn't mean to write so much but Parallax and products listed are my all time favorites, hence my log in name.
