Why not use a TeensyWe've also carry a similar board from PJRC called the Teensy . The Teensy uses the same chip so you may be wondering, why did we design a different-but-still-basically-the-same board? We've used the Teensy in a few projects and like it a lot but there are a few details that we wanted to change. We wanted……a bootloader that would work with avrdude since that is our preferred software…another LED, for power-good indication…a 500mA fuse on the USB power-source pin…mounting holes so we could attach it easily…reprogramming ISP header so we could program the board directly without the bootloader…a larger reset button…all the pins broken out for use with a breadboard…open source bootloader that works with AVRdudeThat doesn't in any way mean that it is better or replaces the Teensy. Here are some reasons we will still use the teensy for many projectsIt's really really small. A third the size of this breakoutThe bootloader that is programmed in uses only 512 bytes (instead of 2K)It works nicely with Teensyduino and auto-resets right before programming
don't want to pay more for shipping costs than for the actual wares smiley-wink
Quotedon't want to pay more for shipping costs than for the actual wares smiley-winkYes, that's an issue, especially for heavy items. One or two Arduino type boards ship for $3.50 with tracking number, but have the other attribute: SLOW..
nano's are GREAT and you can get them all over on ebay etc for like 14 usd they are chepest, and work great! that is what i would use if you dont need a ton of pins or have a huge program
I might consider that (smiley)What exactly is SLOW in your vocabulary ?
( LONG in my vocabulary >= 70 years )
