Typically an Arduino compatible header for serial programming has reset just after the RX/TX so it can be triggered by DTR handshake line from the RS232 adapter. This makes the ATMEGA run the bootloader and talk to the PC. You can press the reset button by hand and let go at the right time but ...
@pixelmike It's not as powerful as a dual core Atom by a long way. It can do a surprising amount though. If you want to run audio stuff though it might be worth paying the extra for a BeagleBoard-xM it's faster and has twice the RAM and most importantly some audio jacks! (the BeagleBone has onl...
