[Noisebridge-discuss] Electronics Question => ATMega328P

[Jake]

for people who want to make an arduino from scratch, i have a number of 
ATMEGA32U4RC-AU chips which are what is used on the Teensy, and the 
Arduino Leonardo.

It has built-in USB (it appears as a serial port on the computer, no USB 
chip needed) but it's in a QFP package - square surfacemount.  It's not 
hard to solder if you have a board, and I am about to get a pile of 
LeOlympia boards for people who want to make their own Leonardos.

The Leonardo bootloader from arduino (which emulates the serial port on 
the USB interface of the chip) is open-source free software, but the 
bootloader on the Teensy is locked down closed-source and they even use 
the hardware fuse lockout so you can't even rip the binary and disassemble 
it.

this is the LeOlympia board, which I will be getting a pile of.  There 
will be kits for building on mondays at CHM if there's enough interest.
