Connections​

NULA DeepsleepSCD43
QwiicQwiic

If you'd rather wire the sensor directly instead of using a Qwiic cable, connect it to the K1 header like this:

NULA DeepsleepSCD43 (K1 header)
3V33V3
GNDGND
SDASDA
SCLSCL
ℹ️
The SCD43 communicates over I2C with a fixed address of 0x62. This address cannot be changed.
