    Which GPIOs can I use - Cirrus Card pinouts for the Extension Header and the UART Header


      The Cirrus card has a 20 pin extension header and a three pin UART header that give access to RPI GPIOs, I2C and UART.


      I had to scrape all this info together for my own projects so I thought I would share.  As usual the info was buried in multiple documents and posts.  Let me know if there are any corrections or additions.


      Plenty O info
