Hive Interface Board

A table of the GPIO pins used by Hivetool sensors is on the GPIO Pinout page.

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


UPS PIco for the DHT11, DHT22 temperature and humidity 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

The UPS PIco is reported to work with Hivetool if you do not use the DHTxx sensors (which use GPIO pins 13 1nd 15)and do not use the DS3231 RTC (which uses I2C address 68.

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.

GPIO-4 and GPIO-17 are used by the 1-Wire bus and the LED.
