AVR junkie paradise

[acidfree:4987]I have been pining for some shiny tiny hardware that would look good in the CW (Morse code) paddle that I am making. Arduino had been a first choice for several days. I was on the verge of buying a couple of boards when I came across PJRC’s Teensy. It really is teensy. But it incorporates a little bit of hardware that I had not seen in a proto-board before: Atmel’s 8-bit MCU with USB support. The Teensy has the Mega32U4 processor at its core, which has 32kB of flash, 2.5kB SRAM, and 1kB EEPROM, support for up to 6 USB full-speed functions, and lots more of the standard AtMega goodies. I think one of the coolest things about this board is that once you have a bootloader in place, you can flash the system over the USB connection that is already has. No need for an extra programmer and more cables. And even if you screw up your application, the bootloader is safe, because it is protected by separate lock bits.

To make a short story even shorter, I ordered two Teensy boards over the weekend and they arrived today. Fast shipping. (It helps that PJRC is less than 20 miles away.)

I am in Atmel junkie paradise.
