gaensli / Icebreaker - History

Added DNP markers to the newly added footprints and ears.

Added "ear" circuits. WS2812 & Shitty Addon.

The "top" ear is a RGB LED connector to WS2812 adapter with level
shifting to 5V. It supports one WS2812 string interface. (there is not
enough space for more channels unfortunately.

The "bottom" ear is a RGB LED connector to Shitty Addon adapter with I2C
pullups. This allows for connecting badgelife shitty addon mini badges
to the iCEBreaker.

Optimized out one 10k placement. Replaced R7 with R2D.

We had a spare 10k resistor in the quad pack used for FTDI flash
pullups, we can use that one instead of a discrete separate placement.

Added RGB LED footprint with voltage supply selector jumper.

Thanks for the suggestion @smunaut
This addition allows the use of CLX6F-FKC Cree RGB LEDs but you can also
mount discrete LEDs or infrared LEDs on the pads. It should provide
additional flexibility for the user. The footprint is not populated by
default.

Added easier way for adding "piggyback" SPI RAM.

Added a pad near the SPI flash CS pin. This pad is connected to ~LEDG.
This will allow us to solder on an SPI RAM chip on top of the SPI flash
chip and connect it's CS line to ~LEDG signal. Allowing us to use the
flash and RAM through the same SPI interface.

This closes #19 for the V1.0c milestone. We will revisit this topic for
V2.0 milestone.

Added jumper from ADBUS3 to ~LEDR. Closes #18

Thanks for the suggestion @smunaut :D
