The Daisy Pi extension board provides input/output connectivity for digital and analog sensors, along with power for each of them, a status led and main voltage feedback.
Digital sensors :
BMP085 – atmospheric pressure and temperature sensor
ADXL345 – accelerometer
Slot 1 IN/OUT ( 3V3 – Gnd – GPIO07 )
Slot 2 IN/OUT ( 3V3 – Gnd – GPIO25 )
Slot A3-A6 ( ADC in, max 3V3 )
Voltage input as A7, internal, for precise main system voltage check ( ~ 5V )
