GPIO Conflicts

Hive Interface Board

If the sensors are not connected and the drivers are not enabled, there should be no conflict.

See GPIO Pinout for a table of the GPIO pins used by Hivetool sensors.

UPS PIco - Uninterruptible Power Supply

UPS PIco - Uninterruptible Power Supply (HV3.0B+) conflicts with the DHT22s which are use GPIO27 (Pin13) & GPIO22 (Pin15).

The UPS PIco Uses the Following Pins

• Serial Port (Firmware Updates): GPIO14 (Pin8) & GPIO15 (Pin10)
• i2c Port: GPIO2 (Pin3) & GPIO3 (Pin5)
• Pulse Train: GPIO27 (Pin13) & GPIO22 (Pin15)

It also uses the I2C addresses 68-6f:

$ i2cdetect -y 1
    0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
