Increase hole size for blue 12 VDC power connector.
Increased from .038" to .042".
Change GPIO pin for LED from pin 7 (default 1-wire) to pin 11.
Add Chip Select to SPI (GPIO 10 SPI0_CE0) to H7.
This is for the AD7124-8 Eval Board. Need Chip Enable (CE) to frame the word.
Hive Interface 0.3
| H7 SPI ver 0.3 | |
|---|---|
| Pin | Signal |
| 1 | +3.3 |

Change pins on H2 I2C so Real Time Clockk (RTC) will plug in.
- Remove +5 VDC from Pin 1.
- Make Pin 4 No Connect (NC)
This will allow the DS3231 to plug into header H2 without modifying the Hive Interface board.
