This fritzing breadboard diagram is straight forward. Here is the line by line summary:
MCU Power:
- Feather [3V] --> Breadboard VCC [Red Power Rail]
- Feather [GND] --> Breadboard GND [Blue Ground Rail]
Mic:
- Max9814 [GND] --> Breadboard [GND]
- Max9814 [Vdd] --> Breadboard [VCC]
- Max9814 [Gain] --> Breadboard [VCC]
- Max9814 [OUT] --> Feather [A0] (analog)
Heart Rate:
- Polar F5 [GND] --> Breadboard [GND]
- Polar F5 [VCC] --> Breadboard [VCC]
- Polar F5 [OUT] --> Feather #11 (digital in)
Light:
- TSL2561 [Vin] --> Breadboard [VCC]
- TSL2561 [GND] --> Breadboard [GND]
- TSL2561 [SDA] --> Feather #2 [SDA]
- TSL2561 [SCL] --> Feather #3 [SCL]
Temp/Humidity:
- DHT22 [VCC] --> Breadboard [VCC]
- DHT22 [OUT] --> Feather #5
Also connect through a 10k Resistor --> Breadboard [VCC] - DHT22 [GND] --> Breadboard [GND]
The wiring and pin connects can be seen a little easier with the OLED display removed.
The Feather 32u4 BLE datasheet summary can be helpful so I've included it below.
