If 20V then [http://uk.farnell.com/on-semiconductor/mbrs410lt3g/schottky-rectifier/dp/1702812 10V/1A] seems a useful diode to rectify 0.5A with low losses. | If 20V then [http://uk.farnell.com/on-semiconductor/mbrs410lt3g/schottky-rectifier/dp/1702812 10V/1A] seems a useful diode to rectify 0.5A with low losses. | ||

All AVR MCUs come with debugWire disabled :( - see [http://www.atmel.com/Images/doc2562.pdf Connecting to a board with JTAG MK2]. | |||
To enable debugWire I need to use ISP/ which needs MISO,MOSI,SCK and RESET, VCC, and GND! Can do with the DIP by programming before putting in the board; using a socket. | |||
I wonder how the users of SMD packages manage it? | |||
