Change: Hive Interface 0.3

• Change GPIO pin for LED from pin 7 (default 1-wire) to pin 11.
• Increase hole size for blue 12 VDC power connector.
• Add Chip Select to SPI (GPIO 10 SPI0_CE0) to H7. This is for the AD7124-8 Eval Board. Currently:

H7 SPI ver 0.3
Pin	Signal
1	+3.3
2	GPIO 14 SPIO CLK
3	GPIO 13 SPIO MISO
4	GPIO 12 SPIO MOSI
5	Ground

H7 SPI ver 0.5
Pin	Signal
1	+3.3
2	GPIO 14 SPIO CLK
3	GPIO 13 SPIO MISO
4	GPIO 12 SPIO MOSI
5	GPIO 10 SPIO CE0
6	Ground

• Change pins on H2 I2C so RTC will plug in. Remove +5 VDC from Pin 1. Move ground on C?. See http://hivetool.org/w/index.php?title=Real_Time_Clock_RTC

Currently:

H2 I2C Bus
Pin	Signal
1	+5
2	+3.3
3	I2C
4	I2C
5	Ground

New (but remove + 5 and make Pin 5 NC:

Old H2 I2C Bus		New H2 for RTC
Pin	Signal	New Pin
1	+5	No connect
2	+3.3	Pin 1 of H2
3	I2C	Pin 2 of H2
4	I2C	Pin 3 of H2
5	Ground	No connect
Ground for C	Ground	Pin 5 of H2

H2 I2C Bus ver 0.5
Pin	Signal
1	+3.3
2	I2XC
3	I2C
4	NC
5	Ground
