I’d like to see the Teensy and Teensy++ sold on SparkFun.
Just order them directly from pjrc, they have great service.
Besides that does not leverage SF forte, SF should design a project board for the 2 products.
Something with a sd card, eeprom, lcd interface, xbee interface.
oh I meant SparkFun should buy from PJRC so I can get more stuff from one place and save some shipping costs.
a Teensy++ with the AT90USB1287 would be better though since it has USB host capabilities
it would hardly be ‘teensy’ anymore with a monster like the AT90USB1287 on it… :roll:

Teensy++ uses AT90USB1286 and the AT90USB1287 has identical pin layout but adds USB host capabilities
i am wrong. you are correct. that would be cool.frank26080115:

I’ve used these; they’re great. Good support bootloader.
Actually the bootloader is impressive at 512 bytes, but that’s really only a good saving on the Teensy but on the Teensy++ there is already 128kb available so the saving isn’t that much, I got one and the first thing I did was get a better bootloader on there (AVR109 compatible CDC bootloader included with LUFA, slightly modified). The original bootloader annoyed me because it basically made the reset switch useless unless the Teensy Loader program was running. Once you get rid of the original bootloader, you cannot get it back as it is close source. I tried obtaining a dump but the chip had the lock bits set so that I can’t.

That is actually one of the main reasons I never bought a Teensy, as much as I like the hardware design. It’s good to know there are alternative AVR-USB bootloaders available.
I use and like the Teensy. Wish SFE would carry it.
As to Atmel bootloaders… here’s one with a nice PC-side Graphical interface. Free. Easy to adapt AVR side code - which is quite small.
