The hardware page for the Mini says the following about the pins:


digital i/o features tpixel.gif  

? all 16 digital and analog pins: GPIO   

? pins 1-3: RS232 TX, RX, DTR   

? pins 9-10: I2C SDA, SCL   

? pins 11-12: UART 1 TX, RX   

? pins 14-16: SPI MOSI, MISO, SPCK   

? pins 17-20: PWM, PWM, PWM, PWM


What is Pin 13? Is it a plain digital I/O pin?

Hi Frode,

Yes, pin 13 is just an extra GPIO for you to use in your project :)

It looks like Pin 13 is a plain digital I/O.

I am basing this on the Mini Pinout card in the Wiki pages that has no special functions listed for pin 13, and the how much current can I draw Wiki page that lists P13 as a digital IO (not a high current one).





Don't you just hate it when someine else gets their answer in while you are typing. :)
