Hive Interface Board
A table of the GPIO pins used by Hivetool sensors GPIO Pinout.
If the sensors are not connected and the drivers are not enabled, there should be no conflict.
For instance, the Wity uses GPIO pins ,
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

Witty Pi Mini Realtime Clock and Power Management
Witty Pi Mini uses GPIO-4, GPIO-17, GPIO-2(SDA 1) and GPIO-3(SCL 1). The usage of GPIO-4 and GPIO-17 are customizable.
