Solar Board Wire Harness

Wires needed -

Photodiode:
- SPI data
- SPI clock
- CS
- 3V3
- GND
Sun sensor:
- SDA
- SCL
- 3V3 (VREF)
- 5V (VCC)
- GND
Temperature sensor:
- SDA
- SCL
- 3V3
- GND
Solar panel:
- VOUT
- GND

Total:

SDA
SCL
3V3
5V
VOUT
GND

8 pin header with 2 lines for VOUT, GND?

S8B-PH-SM4-TB - put one of these on the back of each solar panel

note - VOUT and GND close together to decrease loop size. GND buffer between the I2C lines and power for increased isolation

1	3V3
2	5V
3	VOUT
4	VOUT
5	GND
6	GND
7	SCL
8	SDA

These wires will connect directly to the EPS board. 3V3, 5V, SCL, SDA are all global signals (on the PC-104 stack) so they can be connected on any board. VOUT needs to go directly to EPS to be the input to the MPPT system.
