  • 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


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
