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
