# Uncomment "serial" if using USB, uncomment "canbus_uuid" if using CAN. Edit the serial address or UUID with the correct address/UUID for your PCB.

# serial: /dev/serial/by-id/usb-Klipper_stm32g0b1xx_000000000000000000000000-if00 # < update with the correct serial address
# canbus_uuid: 123456789012 # < update with the correct CAN Bus UUID

# Edit the I2C bus to match which sensors are connected to which connector on the PCB.
# Below is configured for BOTH air intake sensors wired to I2C1 (AKA SENSORS1 on the PCB),
# and BOTH exhaust sensors are wired to I2C2 (AKA SENSORS2 on the PCB).

# i2c_bus        | Connector
# i2c1_PB8_PB9   | SENSORS1
# i2c2_PB10_PB11 | SENSORS2
