UniPi

Description

Major building blocks of UniPi:

• Relays: 8 relays 250VAC@5A or 24VDC@5A – control switching elements

• UART port: Standard serial port to connect serial console or many other devices (NFC

readers, … )

• 1Wire port: Provides 1Wire bus interface to connect 1Wire devices such as temperature and

humidity sensors

• I2C port: For connecting other extension modules for example relay or analog output

modules

• I2C configuration pins: To connect the I2C_0 bus from the RPi (only for advanced users)

• RTC (Real Time Clock) module: Provides real time in case of internet or power outage

(backup battery not included in the package).

• Power 5V: 2.1mm connector for power supply

• RPI connector: 26-pin connector for Raspberry Pi

• Digital inputs: 12(+2) galvanically isolated digital inputs for reading signals from external

devices

• 12V out: Power supply 12V@200mA - only for use with digital inputs of the UniPi

• Configurable ports: To configure digital inputs for use with external power source

• Analog in: Two 0-10V analog inputs for reading analog signals from external devices

• Analog out: One 0-10V analog output for proportional controlling

• AO trimmer: For precise adjustment of the analog output
